Semantic Search
Also known as: vector search
In one line
Search that finds results by meaning, not just matching keywords.
What does Semantic Search mean?
Semantic search uses embeddings to rank results by conceptual similarity. It surfaces "how do I reset my password" for a query of "can't log in".
A real-world example
Searching your help centre for "billing problem" and finding an article titled "Update your payment method".
