How this works: a hand-built inverted index with BM25 ranking, prefix matching on the last token, and Damerau–Levenshtein typo tolerance — the same architecture Meilisearch and Typesense use, running entirely in your browser over a deterministic synthetic catalog. Facet counts are disjunctive (each dimension is counted with every other filter applied). In production I wire the identical UX to PostgreSQL full-text search (tsvector + pg_trgm), Meilisearch or Typesense — the engine changes, the experience doesn't. · SIFT is a portfolio demo; no data leaves this tab.
