Ajoute une fonction SQLite UDF accfold() (app/src/AccentFolding.php) qui plie les caractères accentués latin vers leur base ASCII (é→e, ç→c, …), et l'applique à chaque condition de recherche côté colonne ET côté terme (accfold(column) LIKE accfold(:term)). Comme le runtime n'a ni intl (Normalizer) ni iconv, le repli passe par une map de translitération manuelle (Western Latin-1 + Latin Extended-A, NULL-safe). Couvert : - recherche publique (searchTheses / countSearchResults) : titre, sous-titre, synopsis, auteurs, promoteurs, tags ; - popover étudiant (getThesesByAuthorName / getThesesForAuthors) : a.name ; - recherche backoffice (getThesesList / getThesesListCount) : titre, sous-titre, identifiant, auteur. L'UDF est enregistré dans Database::registerSqliteFunctions() (appelé par le constructeur et par le harnais de test TestDatabaseInstance). Évite aussi la dépréciation PHP 8.5 de PDO::sqliteCreateFunction() : la connexion est créée via \Pdo\Sqlite quand disponible (createFunction()) avec repli sur PDO (sqliteCreateFunction()) sur les anciens runtimes ; les tests passent de @dataProvider docblock à l'attribut #[DataProvider] (fin de la dépréciation PHPUnit). Détache .php-cs-fixer.cache (gitignoré) pour ne plus polluer le working copy. 294 tests PHPUnit verts sans dépréciation, phpstan niveau 5 OK.

# Search & Répertoire — Documentation
|
||
|
||
Two public browsing surfaces, both handled by `app/src/Controllers/SearchController.php`
|
||
and routed by `app/src/Dispatcher.php`:
|
||
|
||
| Route | Handler | Purpose |
|
||
|-------|---------|---------|
|
||
| `/search`, `/search.php` | `handleSearch()` | Full-text query + classic single filters |
|
||
| `/repertoire`, `/repertoire.php` | `handleRepertoire()` | Browseable directory with multi-select filters |
|
||
|
||
Both only ever expose **published** theses (`is_published = 1`).
|
||
|
||
---
|
||
|
||
## HandleSearch (`/search`)
|
||
|
||
`handleSearch()` reads from `$_GET` and renders `app/templates/public/search.php`
|
||
with the results fragment (`app/templates/partials/search-results.php`).
|
||
|
||
Searchable text fields (via `Database::searchTheses()`):
|
||
- Title, subtitle, synopsis, author names, supervisor names, tags/keywords.
|
||
|
||
Single-value filters (`collectSearchParams()`):
|
||
- `query` — free text
|
||
- `year` — exact year
|
||
- `orientation` — artistic orientation
|
||
- `ap_program` — AP program
|
||
- `finality` — finality type
|
||
- `format` — format
|
||
- `keyword` — tag/keyword
|
||
|
||
Results are paginated (`limit = 20` default); the **search bar**
|
||
(`app/templates/partials/search-bar.php`) submits a GET form to `/search`.
|
||
|
||
---
|
||
|
||
## HandleRepertoire (`/repertoire`)
|
||
|
||
`handleRepertoire()` reads multi-select filter arrays from `$_GET` and renders
|
||
`app/templates/public/repertoire.php`, which uses the shared results partial
|
||
and `app/templates/partials/repertoire-index.php`.
|
||
|
||
Multi-select filters (`collectFilterParams()`, each an array, `_GET` keys):
|
||
- `fy[]` — years (validated to 1900–2100)
|
||
- `ap[]` — AP program names
|
||
- `or[]` — orientations
|
||
- `fi[]` — finalities
|
||
- `kw[]` — keywords/tags
|
||
|
||
Each value is trimmed, length-capped (≤ 100), de-duplicated, and passed through
|
||
as sanitised strings — no direct user input reaches SQL.
|
||
|
||
There is also an HTMX **student preview** popover at
|
||
`/repertoire/student-preview` (`handleStudentPreview()` → `student-preview.php`).
|
||
|
||
---
|
||
|
||
## Rate limiting
|
||
|
||
Search is rate-limited via `app/src/RateLimit.php`. See the nginx config
|
||
(`nginx/xamxam.conf`) for the matching server-side limits.
|
||
|
||
---
|
||
|
||
## Database access
|
||
|
||
- **Full-text + single filters:** `Database::searchTheses(array $params, $limit, $offset)`
|
||
and `Database::countSearchResults(array $params)`.
|
||
- **Keyword/tag autocomplete:** `Database::searchTags(string $query)`.
|
||
- **Supervisor autocomplete:** `Database::searchSupervisors($query, $role)`.
|
||
- **Language autocomplete:** `Database::searchLanguages(string $query)`.
|
||
|
||
Queries operate on `v_theses_public`; keyword matching joins the `thesis_tags` /
|
||
`tags` tables (keywords are stored as lowercase-normalised **tags**, not a
|
||
`keywords`/`thesis_keywords` set — see [database.md](database.md)).
|
||
|
||
All queries use PDO prepared statements and escape `%`/`_` for `LIKE`
|
||
(`Database::escapeLikeString`) to prevent wildcard injection.
|
||
|
||
### Accent-insensitive matching
|
||
|
||
Text searches on the public **search bar**, the **student-preview** popover, and
|
||
the **admin list** search are all **diacritic-insensitive**: `Théophile` and
|
||
`Theophile`, `sévère` and `severe` return the same results.
|
||
|
||
This is implemented via a SQLite user-defined function `accfold()`
|
||
(`app/src/AccentFolding.php`, registered in `Database::registerSqliteFunctions()`), which
|
||
strips precomposed accented Latin characters to their ASCII base (`é` → `e`,
|
||
`ç` → `c`, …). Search conditions compare the folded column against the folded
|
||
term (`accfold(column) LIKE accfold(:term)`), so both sides are normalised the
|
||
same way. The function is NULL-safe and registered on the production and test
|
||
connections alike; the public path uses `searchTheses()`/`countSearchResults()`,
|
||
the student popover `getThesesByAuthorName()`, and the admin list
|
||
`getThesesList()`/`getThesesListCount()`.
|
||
|
||
Note: `intl`/`Normalizer` and `iconv` are **not** available on the runtime, so
|
||
folding uses a hand-maintained transliteration map (Western Latin-1 +
|
||
Latin Extended-A).
|
||
|
||

|
||
|
||
## Performance notes
|
||
|
||
- Critical text/filter columns and the junction tables are indexed
|
||
(`idx_theses_pub_year`, `idx_theses_*`, `idx_thesis_tags_*`, …).
|
||
- `v_theses_public` pre-computes the joins for the common read path.
|
||
- The repertoire filters operate on indexed lookup columns.
|
||
|
||

|
||
|
||
## Future enhancements (not yet implemented)
|
||
|
||
The historical `search.md` listed potential automplete/faceted-search/export
|
||
ideas. Status:
|
||
|
||
- Auto-complete for tags exists at the form level (`searchTags`)
|
||
- Faceted counts, saved searches, result export, and advanced boolean operators
|
||
are **not** implemented
