Vector search

Fact

A search method that finds content by meaning, not exact words.

In Plain Words

Vector search is like a librarian for half-remembered thoughts. Say “the space cat thing,” and it still finds the right page.

You meet it in knowledge-base search and recommendations. RAG uses it to find nearby facts first.
