Hybrid Search
Vector similarity and keyword matching run together, then merge — so an exact product code is found as reliably as a paraphrase.
Vector search understands meaning and misses identifiers. Keyword search finds INV-2026-0412 and misses the question that never used those words. Running only one of them is a decision to be bad at half your queries.
Ragenta runs both, deduplicates the candidates, and hands the merged set to the reranker. Every answer shows which passages survived and which fell below the cut.
