Natural-language search

Shoppers don't type filter syntax; they type sentences. A natural-language model parses the free-text query into the filters, sort order and search terms a collection understands — price ceilings, colour, category — before the request ever reaches the index.

It sits in front of ordinary hybrid search rather than replacing it: the parsed filters narrow the candidate set, and typo-tolerant, vector-aware retrieval still ranks what's left.
