Semantic Search
Definition
Search technology that understands the meaning and context of queries rather than just matching keywords.In-Depth Explanation
Semantic search uses embeddings to find conceptually similar content even when exact words differ. It understands synonyms, context, and intent. This approach powers modern search experiences and is fundamental to RAG systems. It dramatically improves search relevance over traditional keyword matching.
Real-World Example
Searching "how to fix slow computer" also returns results about "speeding up PC performance" and "optimizing system speed."
