How builders describe it

The pg-jev author demos jev(), a PostgreSQL extension that filters table rows with natural-language conditions and no index or embeddings, judging 129 rows in about a second.

**I made a fuzzy sql function using jev. ** Ask your database: **WHERE jev(people, 'could work from home')** or **WHERE jev(people, 'name sounds european')** Tada, jev will search and judge the rows using your prompt.

The decision Jev makes

Rank candidates against a query, or answer whether a passage is relevant.

Where it fits

Search pipelines retrieve too much. These projects use Jev as a reranker or relevance check after the first search, so only useful results reach the user or the model. All 108 search & rag projects →
