Semantic Search
Search that understands meaning and intent rather than just matching keywords.
📖 Apprentice Explanation
Semantic search understands what you mean, not just what you type. If you search for 'how to fix a slow computer,' it finds results about performance optimization even if they don't use those exact words.
🧙 Archmage Notes
Semantic search uses embedding models to convert queries and documents to vectors, then finds nearest neighbors. Hybrid approaches combine semantic and keyword search (BM25). Used in RAG systems, knowledge bases, and modern search engines.
