122	122	- Save an answer: `/save` writes the last answer to a Markdown file; with `saveAnswerTool: true`, the model does it itself when you ask in your own words (`save_answer`). Never overwrites a file. See [Save an answer to a file](docs/en/how-to/save-an-answer.md).
123	123	- Unload a model: `/unload [model]` frees a model from the server's memory — in the terminal, the window and an editor —, and the `unload_model` tool lets the agent do it itself, e.g. on another agent's model once it has answered; llmman, Ollama and llama-server in router mode. `unloadModels: false` turns both off. See [Free a model's memory](docs/en/how-to/unload-a-model.md) and `demos/unload-models/`.
	124	+- Search a documentation folder: `/docs <words>` searches the text files of the folders named in `docSearch.dirs` (`.md`, `.adoc`, `.txt`… — only the extensions listed) and returns the best passages with their `path:line` link, ranked with BM25 — no index, no model (`docSearch.searchDocs`); the `search_docs` tool lets the model do it before it answers (`docSearch.autoSearchDocs`); both off by default. See [Search a documentation folder](docs/en/how-to/search-the-docs.md) and `demos/docs-search/`.
124	125	- Search earlier sessions: with sessions on, `/memory <words>` searches the project's stored conversations (`sessions.searchMemory`), and the `search_memory` tool lets the model do it when a question refers to something decided before (`sessions.autoSearchMemory`); both off by default. The search matches words, not meanings. See [Search earlier sessions](docs/en/how-to/search-earlier-sessions.md) and `demos/memory-search/`.
125	126	- Docker Sandboxes: the sandbox kit lives in its own repository, [mini-me-kit](https://rickub.com/bots-garden/mini-me-kit); `sbx/` explains how to use it (`sbx run …`), with two mixins (`go-toolchain`, `cli-tools`) and ready-made configurations — see `sbx/README.md` and [Run mini-me in a Docker Sandbox](docs/en/how-to/run-in-a-docker-sandbox.md).

  - **Plans**: the built-in `plan` tool lets the agent turn a list of tasks into a tracked plan and show its progress after each answer. See [Manage plans and tasks](docs/en/how-to/manage-plans-and-tasks.md).
  - **Save an answer**: `/save` writes the last answer to a Markdown file; with `saveAnswerTool: true`, the model does it itself when you ask in your own words (`save_answer`). Never overwrites a file. See [Save an answer to a file](docs/en/how-to/save-an-answer.md).
  - **Unload a model**: `/unload [model]` frees a model from the server's memory — in the terminal, the window and an editor —, and the `unload_model` tool lets the agent do it itself, e.g. on another agent's model once it has answered; llmman, Ollama and llama-server in router mode. `unloadModels: false` turns both off. See [Free a model's memory](docs/en/how-to/unload-a-model.md) and `demos/unload-models/`.
++- **Search a documentation folder**: `/docs <words>` searches the text files of the folders named in `docSearch.dirs` (`.md`, `.adoc`, `.txt`… — only the extensions listed) and returns the best passages with their `path:line` link, ranked with BM25 — no index, no model (`docSearch.searchDocs`); the `search_docs` tool lets the model do it before it answers (`docSearch.autoSearchDocs`); both off by default. See [Search a documentation folder](docs/en/how-to/search-the-docs.md) and `demos/docs-search/`.
  - **Search earlier sessions**: with sessions on, `/memory <words>` searches the project's stored conversations (`sessions.searchMemory`), and the `search_memory` tool lets the model do it when a question refers to something decided before (`sessions.autoSearchMemory`); both off by default. The search matches words, not meanings. See [Search earlier sessions](docs/en/how-to/search-earlier-sessions.md) and `demos/memory-search/`.
  - **Docker Sandboxes**: the sandbox kit lives in its own repository, [mini-me-kit](https://rickub.com/bots-garden/mini-me-kit); `sbx/` explains how to use it (`sbx run …`), with two mixins (`go-toolchain`, `cli-tools`) and ready-made configurations — see `sbx/README.md` and [Run mini-me in a Docker Sandbox](docs/en/how-to/run-in-a-docker-sandbox.md).

	70	+- C'est le modèle qui traduit, pas la recherche. Les tutoriels sont en anglais et la recherche porte sur les mots : des mots français ne trouveraient rien. Invité à chercher « avec des mots anglais — noms de widgets et de types », le modèle a transformé les deux questions en français en recherches en anglais à chaque fois, et a répondu en français.
	71	+- Ce que le prompt a dû dire. Sans « toute question sur une application terminal … est une question Ratatui, même quand elle ne nomme pas Ratatui », la question sur Windows recevait une réponse générique, sans recherche (3/3).

++# Démo mini-me : répondre à partir d'un dossier de documentation
++
++*[English version](README.en.md)*
++
++Rata aide à construire des interfaces en mode terminal en Rust avec [Ratatui](https://ratatui.rs). Il ne sait rien de Ratatui par lui-même qui mérite confiance : avant de répondre, il cherche dans `docs/` — neuf tutoriels courts — avec l'outil `search_docs`, répond à partir des passages qu'il reçoit et donne leur lien `chemin:ligne`. Vous pouvez chercher vous-même dans le même dossier avec `/docs <mots>`. La recherche est un BM25 sur les fichiers Markdown : ni index, ni modèle. Le modèle de chat est Qwen3.5 4B, servi par [llmman](https://github.com/llmmanorg/llmman).
++
++## Contenu
++
++| Fichier | Rôle |
++|---|---|
++| `agent.yaml` | Rata : `docSearch` avec `searchDocs: true` (la commande `/docs`) et `autoSearchDocs: true` (l'outil `search_docs`) sur `docs/`, `.md` seulement ; `read_file` pour ouvrir un tutoriel entier, `write_file` pour écrire un programme ; pas de `bash`. |
++| `docs/` | Neuf tutoriels Ratatui 0.30 — premiers pas, layout, blocs et paragraphes, listes, tableaux, jauges et ticks, onglets, état de l'application et événements, popups — et leur index. Chacun contient un programme complet. |
++| `check-tutorials.sh` | Compile chaque programme complet de `docs/` (et `snippets.rs`, les expressions citées dans le texte) avec la ratatui 0.30 actuelle, dans un conteneur `rust` jetable, avertissements traités comme des erreurs. Ne demande que Docker. |
++| `snippets.rs` | Les petites expressions que citent les tutoriels, pour que le texte ne puisse pas s'écarter de l'API. |
++
++## Lancer la démo
++
++```bash
++llmman pull hf.co/unsloth/Qwen3.5-4B-GGUF:Q4_K_M
++cd demos/docs-search
++mm -tui agent.yaml
++```
++
++Chercher à la main :
++
++```text
++/docs liststate
++```
++
++```text
++🔎 5 passage(s) for "liststate" — 10 file(s) in docs
++
++── docs/04-lists.md:5 · Lists and selection › Keep the selection with ListState
++## Keep the selection with ListState
++
++`ListState` remembers which item is selected and how far the list is scrolled. …
++```
++
++Puis demander à Rata :
++
++```text
++How do I keep the selected item of a List in ratatui?
++Every key I press acts twice on Windows. Why?
++Comment afficher un tableau avec une ligne sélectionnée ?
++Write src/main.rs: a list of three fruits I can move through with the arrow keys, q to quit.
++```
++
++Chaque recherche s'affiche sous la forme `📚 search_docs: "<mots>"` suivie des passages. Vérifiez que les tutoriels compilent toujours avec `./check-tutorials.sh` (`OK: 10 programs compile against ratatui 0.30.2` le 2026-10-20).

++## Résultats mesurés (2026-10-20, `mm -p`, llmman)
++
++Qwen3.5 4B Q4_K_M, `temperature: 0`, réflexion désactivée, cet `agent.yaml`, une copie neuve de la démo à chaque exécution. Trois exécutions par question ; la même recherche et la même réponse à chaque fois.
++
++| Question | Recherché | Réponse | Lien donné | |
++|---|---|---|---|---|
++| How do I keep the selected item of a List in ratatui? | `List selected item index` | `ListState`, `render_stateful_widget`, `state.selected()` | `docs/04-lists.md:5` | 3/3 |
++| How do I show a popup in the middle of the screen? | `popup center middle screen` | `Clear` d'abord, puis le dialogue dans une zone centrée | aucun | 3/3 |
++| Every key I press acts twice on Windows. Why? | `Windows key repeat double press` | événements Press et Release ; tester `KeyEventKind::Press` | `01-getting-started.md:15`, `03-blocks-and-paragraphs.md:11` (du code qui fait ce test), pas le passage qui l'explique, `08-app-state-and-events.md:60` — que la recherche avait classé premier | 3/3 |
++| How can I animate a progress bar without waiting for a key? | `animate progress bar key event` | `Gauge` + `event::poll` avec délai, un tick quand rien n'arrive | `docs/06-gauges-and-ticks.md:9` | 3/3 |
++| Comment découper l'écran en en-tête, corps et pied de page ? | `header footer body layout` | `Layout::vertical` avec `Length` / `Min`, en français | `docs/02-layout.md:16` | 3/3 |
++| Comment afficher un tableau avec une ligne sélectionnée ? | `table selection line` | `Table` + `TableState` + `row_highlight_style`, en français | `docs/05-tables.md:1` | 3/3 |
++| Write src/main.rs: a list of three fruits I can move through with the arrow keys, q to quit. | `list widget` | `src/main.rs` écrit — il **compile** avec ratatui 0.30.2 (vérifié dans le conteneur `rust`) | — | 3/3 |
++| Bonjour, qui es-tu ? | — | une ligne, en français, sans recherche | — | 3/3 |
++| What is the capital of Japan? One word. | — | `Tokyo`, sans recherche | — | 3/3 |
++
++De 14 à 38 s par question avec recherche, moins de 2 s sans ; deux exécutions ont pris 164 s et 316 s avec la même réponse que les autres (cause non établie — le serveur de modèles est partagé). Une recherche dans `docs/` prend environ 1 ms.
++
++## Bon à savoir
++
++- **C'est le modèle qui traduit, pas la recherche.** Les tutoriels sont en anglais et la recherche porte sur les mots : des mots français ne trouveraient rien. Invité à chercher « avec des mots anglais — noms de widgets et de types », le modèle a transformé les deux questions en français en recherches en anglais à chaque fois, et a répondu en français.
++- **Ce que le prompt a dû dire.** Sans « toute question sur une application terminal … est une question Ratatui, même quand elle ne nomme pas Ratatui », la question sur Windows recevait une réponse générique, sans recherche (3/3). Avec cette phrase, les autres réponses sont restées justes, mais la réponse sur la popup a cessé de donner son lien (elle donnait `02-layout.md:68` et `09-popups.md:9` avant) — les citations d'un petit modèle bougent avec le prompt.
++- **Les liens sont des `chemin:ligne`** : un éditeur les ouvre, et `read_file` lit le tutoriel entier quand un passage ne suffit pas.
++- **Chaque interrupteur séparément.** `searchDocs` vous donne `/docs` ; `autoSearchDocs` donne `search_docs` au modèle. Les deux sont désactivés par défaut.

++`Row::new(vec!["Dune", "Herbert", "1965"])` is a row of cells. `Table::new(rows, widths)` needs the column widths as constraints, the same ones as `Layout`: `[Constraint::Fill(2), Constraint::Fill(1), Constraint::Length(4)]`. `.header(Row::new(...))` adds a header row, `.column_spacing(2)` the space between columns.
++
++## Select a row with TableState
++
++`TableState` works like `ListState`: `select_next`, `select_previous`, `selected`. Style the selected row with `.row_highlight_style(...)` and mark it with `.highlight_symbol("> ")`.

++
++## Cells with their own style
++
++A cell can be styled on its own: `Cell::from("overdue").red()`, then `Row::new(vec![Cell::from("Dune"), Cell::from("overdue").red()])`. A whole row too: `Row::new(...).on_dark_gray()`. `.height(2)` gives a row two lines.

++# Popups and dialogs
++
++A popup is drawn over the rest of the UI, in a smaller area, after everything else. Ratatui draws in order: what is rendered last is on top.
++
++## Clear the area first
++
++Widgets only paint the cells they use, so the UI underneath would show through the popup. Render `Clear` on the popup's area first: it blanks it, then draw the popup's block and content in the same area.
++
++## A centered confirmation dialog

	1	+# Documentation search — explanation
	2	+
	3	+## What is this about?
	4	+
	5	+`/docs` and the `search_docs` tool (ticket 106) search the text files of some folders and return passages — a section of a page, with its heading path and its `path:line` link. They answer a different need from [`search_memory`](persistent-sessions.md): the stored sessions hold what was said and decided; a documentation folder holds what is written and maintained. The two searches are separate tools on purpose, with separate engines.
	6	+
	7	+## Why BM25, and no model
	8	+
	9	+The search ranks passages with BM25, the scoring of most full-text engines: a word counts more when it is rare in the folder and when it appears often in the passage, and long passages are not favoured for being long. It needs no model. The alternatives looked at (ticket 104) — `qmd`'s vector and hybrid modes, embedding-based tools — find passages by meaning, across languages and synonyms, but load one to three extra models (300 MB to 2 GB for `qmd query`) next to the chat model, on machines where memory is what runs out first. `qmd search`, its BM25 mode, is the closest equivalent of what mm does, and it needs Node or Bun, an index to build and keep up to date.
	10	+
	11	+BM25 also fixes what made the stored-session search noisy at first: there, every word counted the same, so a short common word matched nearly every message. With BM25 a word found everywhere weighs almost nothing by itself.
	12	+
	13	+## Why no index
	14	+
	15	+The folders are read at every call. mm's own `docs/` — 137 Markdown files, 1.3 MB, 1,320 passages — is read, cut and scored in about 45 ms; the ten files of the demo (44 passages) in about 1 ms (measured 2026-10-20, best of ten runs). An index would make that faster and add what an index brings: a place to store it, a step to rebuild it, and answers that are wrong between a change and the rebuild. For a documentation folder, read when a question needs it, a scan is fast enough and never stale.
	16	+
	17	+## Why passages are sections
	18	+
	19	+A hit is meant to be read by the model, so it must be a unit of meaning that fits next to four others: a section — a heading and what follows it — is what the author wrote as one. Its heading path ("Lists and selection › Keep the selection with ListState") says what it is about even when its text does not repeat it, which is why heading words weigh more. A long section is cut at blank lines, never inside a code block: half a program helps no one. The link points at the passage's first line, so the model can `read_file` the whole page when a passage is not enough.
	20	+
	21	+## Why prefixes, and no stemming
	22	+
	23	+Words of four letters or more also match longer words (`list` → `ListState`) and plurals (`widgets` → `widget`). That is a cheap answer to the commonest misses, for any language. A real stemmer would do better for one language and worse for the others, and would be one more dependency.
	24	+
	25	+## What it does not do
	26	+
	27	+It matches words, not meanings. "Comment découper l'écran ?" finds nothing in English tutorials. In the demo, a 4B model told to search with the documentation's words translated the question itself — "header footer body layout" — every time (6 of 6 French questions); the search did not have to.
	28	+
	29	+## How it relates to the rest
	30	+
	31	+`internal/docsearch` holds the engine (passages, BM25, the walk through the folders) and depends only on `internal/config` and `internal/textfold`, the case-and-accent folding it shares with the stored-session search. `/docs` is in the shared command table; the REPL, the window and the ACP façade each answer it from their working directory. `search_docs` is declared in `main.go` beside the other built-in tools.

	1	+# How to search a documentation folder
	2	+
	3	+This guide shows how to search the text files of a folder — Markdown, AsciiDoc, plain text — by hand with `/docs`, or by letting the model search with its `search_docs` tool before it answers. The search ranks passages with BM25 and loads no model.
	4	+
	5	+## Search by hand
	6	+
	7	+1. Turn the command on and name the folders, in the agent's YAML:
	8	+
	9	+ ```yaml
	10	+ docSearch:
	11	+ searchDocs: true
	12	+ dirs: [docs]
	13	+ extensions: [.md]
	14	+ ```
	15	+
	16	+2. Start mm — the terminal, the window (`mm -tui`) or an editor — and type the words you are looking for:
	17	+
	18	+ ```text
	19	+ /docs liststate
	20	+ ```
	21	+
	22	+ ```text
	23	+ 🔎 5 passage(s) for "liststate" — 10 file(s) in docs
	24	+
	25	+ ── docs/04-lists.md:5 · Lists and selection › Keep the selection with ListState
	26	+ ## Keep the selection with ListState
	27	+
	28	+ `ListState` remembers which item is selected and how far the list is scrolled. …
	29	+ ```
	30	+
	31	+Each passage starts with its link, `path:line`, which an editor opens and `read_file` reads. The model is not called and the conversation is not changed.
	32	+
	33	+## Let the model search
	34	+
	35	+1. Declare the tool:
	36	+
	37	+ ```yaml
	38	+ docSearch:
	39	+ autoSearchDocs: true
	40	+ dirs: [docs]
	41	+ extensions: [.md]
	42	+ ```
	43	+
	44	+2. Tell the model, in its `system` prompt, when to call it and how to quote what it finds. What worked on a 4B model:
	45	+
	46	+ ```yaml
	47	+ system: \|
	48	+ For any question the documentation may cover, call search_docs first, with English
	49	+ words — type and function names work best. Answer from the passages it returns,
	50	+ and end with the link of the passage you used (path:line).
	51	+ ```
	52	+
	53	+The two switches are independent: `searchDocs` alone gives you the command and the model no tool; `autoSearchDocs` alone the reverse.
	54	+
	55	+## Variants
	56	+
	57	+- Several folders, several formats. `dirs: [docs, guides, /shared/handbook]`, `extensions: [.md, .adoc, .txt]`. Only the listed extensions are read.
	58	+- Over ACP. Relative folders are resolved against the session's `cwd`: the project the editor opened.
	59	+- Large files. Files above `maxFileSize` (default `1MB`) are skipped; raise it, or split the file.
	60	+- Questions in another language. The search matches words, not meanings. Documentation in English searched with French words finds nothing — ask the model to search with the documentation's words (see the prompt above), which a small model did reliably in `demos/docs-search/`.

++1. Declare the tool:
++
++   ```yaml
++   docSearch:
++     autoSearchDocs: true
++     dirs: [docs]
++     extensions: [.md]
++   ```
++
++2. Tell the model, in its `system` prompt, when to call it and how to quote what it finds. What worked on a 4B model:
++
++   ```yaml
++   system: |
++     For any question the documentation may cover, call search_docs first, with English
++     words — type and function names work best. Answer from the passages it returns,
++     and end with the link of the passage you used (path:line).
++   ```
++
++The two switches are independent: `searchDocs` alone gives you the command and the model no tool; `autoSearchDocs` alone the reverse.
++
++## Variants
++
++- **Several folders, several formats.** `dirs: [docs, guides, /shared/handbook]`, `extensions: [.md, .adoc, .txt]`. Only the listed extensions are read.
++- **Over ACP.** Relative folders are resolved against the session's `cwd`: the project the editor opened.
++- **Large files.** Files above `maxFileSize` (default `1MB`) are skipped; raise it, or split the file.
++- **Questions in another language.** The search matches words, not meanings. Documentation in English searched with French words finds nothing — ask the model to search with the documentation's words (see the prompt above), which a small model did reliably in `demos/docs-search/`.

  | ACP and window | Tool call of kind `other`; a `cannot unload` result is a failed call. |

++## `search_docs`
++
++Declared when `docSearch.autoSearchDocs` is true (default false). The same search, for the user, is the `/docs <words>` command (`docSearch.searchDocs`, see [slash commands](slash-commands.md)).
++
++| Field | Type | Description |
++|-------|------|-------------|
++| `query` | string | The words to look for. |
++| `limit` | integer | How many passages at most. `0` or absent: 5; capped at 20. |
++
++| Aspect | Behaviour |
++|--------|-----------|
++| Where | The files of `docSearch.dirs` whose extension is in `docSearch.extensions`, recursively, within `docSearch.maxFileSize` (see [configuration](configuration.md#docsearch-keys)). Relative folders are resolved against the working directory: the process directory in terminal mode, the session `cwd` in ACP mode and the window. Read at every call: no index. |
++| Passages | A Markdown (`.md`, `.markdown`) or AsciiDoc (`.adoc`, `.asciidoc`, `.asc`) file is cut at its headings (`#`… / `=`…), headings inside code fences or listing blocks ignored; a passage keeps its heading path. Any other file is cut at blank lines only. A passage longer than 1,500 characters is cut at blank lines outside fences; a single longer paragraph or code block stays whole. |
++| Matching | Words are letters and digits, compared without case or accents. A query word of 4 letters or more also matches a longer word it starts (`list` → `ListState`) and a word it extends by one or two letters (`widgets` → `widget`). Query words of 1 or 2 letters are left out when the query has longer ones. |
++| Ranking | BM25 (k1 1.2, b 0.75) over all the passages of the folders; the words of a passage's heading path count two extra times. Ties: path, then line. Passages holding none of the words are never returned. |
++| Result | `🔎 N passage(s) for "<query>" — F file(s) in <dirs>`, then per passage `── <path>:<line> · <heading › subheading>` and the passage as written, lines kept. `<path>` is relative to the working directory when the file is inside it, absolute otherwise; `<line>` is the passage's first line.

	5	+`/docs` et l'outil `search_docs` (ticket 106) cherchent dans les fichiers texte de dossiers et renvoient des passages — une section d'une page, avec le chemin de ses titres et son lien `chemin:ligne`. Ils répondent à un autre besoin que [`search_memory`](persistent-sessions.md) : les sessions enregistrées contiennent ce qui a été dit et décidé ; un dossier de documentation contient ce qui est écrit et maintenu. Les deux recherches sont des outils séparés, avec des moteurs séparés, volontairement.
	6	+
	7	+## Pourquoi BM25, et aucun modèle
	8	+
	9	+La recherche classe les passages avec BM25, le calcul de score de la plupart des moteurs plein texte : un mot compte davantage quand il est rare dans le dossier et fréquent dans le passage, et un passage long n'est pas favorisé parce qu'il est long. Il n'a besoin d'aucun modèle. Les alternatives étudiées (ticket 104) — les modes vectoriel et hybride de `qmd`, les outils à embeddings — trouvent les passages par le sens, entre langues et synonymes, mais chargent un à trois modèles de plus (de 300 Mo à 2 Go pour `qmd query`) à côté du modèle de chat, sur des machines où c'est la mémoire qui manque en premier. `qmd search`, son mode BM25, est l'équivalent le plus proche de ce que fait mm, et il demande Node ou Bun, un index à construire et à tenir à jour.
	10	+
	11	+BM25 corrige aussi ce qui rendait au début la recherche dans les sessions bruyante : là, chaque mot comptait autant, si bien qu'un mot court et courant correspondait à presque tous les messages. Avec BM25, un mot présent partout ne pèse presque rien à lui seul.
	12	+
	13	+## Pourquoi pas d'index
	14	+
	15	+Les dossiers sont lus à chaque appel. Le `docs/` de mm — 137 fichiers Markdown, 1,3 Mo, 1 320 passages — est lu, découpé et noté en 45 ms environ ; les dix fichiers de la démo (44 passages) en 1 ms environ (mesuré le 2026-10-20, meilleur de dix essais). Un index irait plus vite et apporterait ce qu'apporte un index : un endroit où le stocker, une étape pour le reconstruire, et des réponses fausses entre une modification et la reconstruction. Pour un dossier de documentation lu quand une question le demande, un parcours suffit et n'est jamais périmé.
	16	+
	17	+## Pourquoi des passages qui sont des sections
	18	+
	19	+Un résultat est fait pour être lu par le modèle ; il doit donc être une unité de sens qui tient à côté de quatre autres : une section — un titre et ce qui le suit — est ce que l'auteur a écrit d'un tenant. Le chemin de ses titres (« Lists and selection › Keep the selection with ListState ») dit de quoi elle parle même quand son texte ne le répète pas, d'où le poids supplémentaire des mots de titre. Une section longue est recoupée aux lignes vides, jamais à l'intérieur d'un bloc de code : la moitié d'un programme n'aide personne. Le lien pointe sur la première ligne du passage, pour que le modèle puisse lire la page entière avec `read_file` quand un passage ne suffit pas.
	20	+
	21	+## Pourquoi des préfixes, et pas de racinisation
	22	+
	23	+Les mots de quatre lettres ou plus trouvent aussi les mots plus longs (`list` → `ListState`) et les pluriels (`widgets` → `widget`). C'est une réponse peu coûteuse aux manques les plus courants, quelle que soit la langue. Un vrai raciniseur ferait mieux pour une langue et moins bien pour les autres, et serait une dépendance de plus.

++| Où | Les fichiers de `docSearch.dirs` dont l'extension figure dans `docSearch.extensions`, récursivement, dans la limite de `docSearch.maxFileSize` (voir [configuration](configuration.md#clés-de-docsearch)). Les dossiers relatifs sont résolus par rapport au répertoire de travail : celui du processus en mode terminal, le `cwd` de la session en mode ACP et dans la fenêtre. Lus à chaque appel : pas d'index. |
++| Passages | Un fichier Markdown (`.md`, `.markdown`) ou AsciiDoc (`.adoc`, `.asciidoc`, `.asc`) est découpé à ses titres (`#`… / `=`…), les titres dans les blocs de code ou de listing étant ignorés ; un passage garde le chemin de ses titres. Tout autre fichier n'est découpé qu'aux lignes vides. Un passage de plus de 1 500 caractères est recoupé aux lignes vides hors blocs de code ; un paragraphe ou un bloc de code plus long reste entier. |
++| Correspondance | Les mots sont les lettres et les chiffres, comparés sans tenir compte de la casse ni des accents. Un mot de la requête de 4 lettres ou plus trouve aussi un mot plus long qu'il commence (`list` → `ListState`) et un mot qu'il prolonge d'une ou deux lettres (`widgets` → `widget`). Les mots d'une ou deux lettres sont ignorés quand la requête en contient de plus longs. |
++| Classement | BM25 (k1 1,2, b 0,75) sur tous les passages des dossiers ; les mots du chemin de titres d'un passage comptent deux fois de plus. Égalités : chemin, puis ligne. Un passage qui ne contient aucun des mots n'est jamais renvoyé. |
++| Résultat | `🔎 N passage(s) for "<requête>" — F file(s) in <dossiers>`, puis par passage `── <chemin>:<ligne> · <titre › sous-titre>` et le passage tel qu'il est écrit, lignes conservées. `<chemin>` est relatif au répertoire de travail quand le fichier s'y trouve, absolu sinon ; `<ligne>` est la première ligne du passage. Aucun passage : `🔎 no passage for "<requête>" — F file(s) in <dossiers>`. Une requête vide : `⚠️ nothing to search: give one or more words`. Un dossier absent ajoute `⚠️ <rép>: no such folder` avant l'en-tête. Plafonné par `maxOutput`. |
++| Permission | Jamais demandée, même avec `yolo: false` : l'outil ne fait que lire. |
++| Affichage terminal | `📚 search_docs: "<requête>"`, puis le résultat. |
++| ACP et fenêtre | Appel d'outil de type `search`. |
++
  ## `search_memory`
  Déclaré quand `sessions.enabled` et `sessions.autoSearchMemory` valent tous deux true (les deux valent false par défaut). La même recherche, pour l'utilisateur, est la commande `/memory <mots>` (`sessions.searchMemory`, voir [commandes](slash-commands.md)).
