Capabilities

Relevant results

Ranking blends term frequency and field weights, with typo tolerance so near-misses still match.

Fast indexing

Documents are searchable moments after they're added; incremental updates don't rebuild the world.

Facets & filters

Narrow results by tags, ranges, and categories in the same query that runs the search.
