Semantic search

Semantic search uses embeddings to match a query to documents by meaning, so a search for “reset my password” can surface a doc titled “account recovery” even with no shared keywords.

It typically augments rather than fully replaces keyword search; hybrid approaches combine semantic similarity with traditional lexical matching and re-ranking for the best results.

Modernizing legacy keyword search with a semantic layer is a common entry point that often grows into a broader RAG or retrieval platform.
