How search works
Moonjar searches your library three ways. By default it picks the right one for the query you typed; you can also force a specific mode.
How it works
Section titled “How it works”Auto (the default)
Section titled “Auto (the default)”Moonjar tries full-text first. If that returns no results, it falls back to semantic search. This combination handles most queries — exact strings hit full-text, vague recall falls through to semantic.
Full-text
Section titled “Full-text”A Postgres tsvector index over the source text of every document.
Tokenises words, stems them, and ranks results with ts_rank. Returns
highlighted snippets so you can see why a result matched.
Best for:
- Unique strings (booking references, postcodes, IDs).
- Quoted phrases.
- Anything where the exact word matters.
Semantic
Section titled “Semantic”A vector index over an embedding of every document. Queries get embedded the same way and results are ranked by cosine similarity — closer in meaning ranks higher.
Best for:
- Vague recall — “that thing about retirement plans”.
- Cross-language matches.
- Concepts that don’t share words with the document.
Structured
Section titled “Structured”A direct lookup against the extracted fields
on every document. Matches against a field name (vendor, total,
provider) or a value substring.
Best for:
- “all my Vodafone bills” (vendor = Vodafone).
- Lookups by exact field value.
What gets searched
Section titled “What gets searched”Documents and their extracted fields. The command palette extends this across memories, reminders, collection items, and conversations — five entity types in one ranked result list.
Group-shared items are searched alongside your own.
Limits
Section titled “Limits”- Auto-mode falls back from full-text to semantic when full-text returns nothing — so a query that matches one document by an obscure word will still surface that document.
- Search is per-account. You don’t see other users’ documents unless they’re shared with you through a group.
- Search inside attachments depends on whether the attachment text was extracted at capture (PDFs and images: yes; raw binaries: no).
