What Semantic Search does

Semantic Search transforms how you find information in your own data. Instead of exact keyword matches, it understands the meaning behind your queries and finds conceptually relevant results. Powered by state-of-the-art embedding models with hybrid search (vector + BM25), reranking, and intelligent filtering.

Frequently asked questions

How is this different from regular search?

Regular search matches keywords. Semantic search understands meaning — searching 'how to fix auth issues' also finds docs about 'resolving login problems'.

How fast is it?

Sub-100ms for collections up to 1M documents. Larger collections use approximate nearest neighbors for similar speed.

How do I install Semantic Search?

Run `npx clawhub@latest install semantic-search` from any directory with Claude Code or OpenClaw installed. The skill is added to your local SKILL.md registry and is available to your agent immediately — no restart required.
