Semantic Search

Search that understands meaning and intent rather than just matching keywords.

Definition

Search that understands meaning and intent rather than just matching keywords. Uses embeddings to find results that are conceptually similar to the query, even if they use different words. Searching for 'how to fix a slow computer' would match 'speed up your PC performance.' Powers modern search and RAG systems.
