vector search

noun

1. A search technique that finds items by comparing the mathematical similarity of their embedding vectors rather than matching keywords. Results are ranked by semantic closeness, so a query about 'orbital debris cleanup' can surface filings that use different terminology like 'active debris removal' or 'post-mission disposal.'
2. Vector search databases (Pinecone, pgvector, Qdrant) store and index embeddings for fast approximate nearest-neighbor lookups, making them a core component of RAG architectures and semantic search systems.
