Search

BM25 full-text search is available on the Free tier with no Ollama required.

Using search

1. Click Search in the navigation bar
2. Type a phrase or keyword — results appear as you submit
3. Results show the source document, page number, a text excerpt, and a BM25 relevance score

Filtering by document

Use the document selector to restrict results to one or more specific books. This is useful when your library spans many documents and you know which one contains the answer.

BM25 scoring

BM25 (Best Match 25) ranks pages by term frequency weighted against how rare each term is across the whole corpus. A page that uses your query term frequently AND that term is rare across all documents ranks highest.

Tip

For short queries like "chimes" or "protocol", BM25 tends to surface later chapters where the term appears repeatedly in action scenes. If you want the introductory definition, try a longer phrase like "what are the chimes" to give BM25 more signal.

Hybrid search (requires Ollama)

When Ollama is configured, the Chat endpoint uses hybrid search behind the scenes: BM25 results are merged with semantic vector results using a 50/50 score blend. The Search page always uses BM25 only.
