Retrieval, Memory & Knowledge
Semantic Search
Searching by meaning and intent rather than exact keyword matching.
Definition
Traditional search finds documents that contain the exact words in your query. Semantic search finds documents that are relevant in meaning — even if they use different vocabulary. If you search for 'contract end date,' semantic search will also surface documents containing 'expiry date,' 'termination date,' or 'agreement renewal date.' This makes AI-powered search dramatically more useful for finding information in large, varied document sets.
