-## Package search
-
-The package search combines several strategies, tried in this order:
-
-1. **Exact package name**: Searching for `vim` shows exactly this
-   package without calling any external service.
-2. **Name prefix matches**: Packages whose name starts with the query
-   rank first, e.g. searching for `sqlite` promotes `sqlite3`,
-   `sqlitebrowser` and friends above all other results.
-3. **Compound word splitting**: Packages whose name contains *all*
-   query tokens match too, so `sqlite browser` finds `sqlitebrowser`.
-4. **Semantic search**: The query is embedded via the vector service
-   (all-MiniLM-L6-v2, 384 dimensions) and the nearest neighbors among
-   the package description embeddings are returned, using the pgvector
-   extension with an HNSW cosine index. Embeddings are computed from
-   the package description and long description and can be (re-)built
-   with `bin/rails debshots:compute_vectors`.
-5. **Full-text fallback**: If the vector service cannot be reached,
-   classic PostgreSQL full-text search takes over.
-
-Queries that share no vocabulary with the package data (gibberish,
-keyboard mash) return an honest empty result instead of random
-semantic matches.
-
-**Why is this package in my results?** Each result knows which search
-strategy produced it. The controller exposes this as
-`@search_sources` (a hash mapping package ids to `:exact`,
-`:name_prefix`, `:name_contains`, `:semantic` or `:fulltext`). For
-debugging you can render a small badge on every result card by adding
-`show_sources=1` to the URL, e.g.
-`https://screenshots.debian.net/packages?search=sqlite&show_sources=1`.
-
-Package pages also show semantically **related packages**, computed as
-a nearest neighbor query against the package's own description
-embedding - no external service call involved.
