# Knowledge searches

On an agent, add a knowledge search so it can look things up in a knowledge base.

Open the agent, then **Knowledge searches**. The page says **What** that agent **can look up in your company's knowledge bases.** The section is **Searches** that agent **can run**. Each search is a tool the agent can use. The note says **Try changes in Test; they go live with the next publish.**

## Add a search

- Choose **New search**.
- **Knowledge base**, then **Name (the tool's name)**.
- **When** the agent **uses it (the tool's description)**.
- **Mode** is **Search when it needs to** or **Always look it up before answering**.
- **Create search**.

## Focus

**Focus** narrows what the search may read: **Tags**, **Types** (the note says **FAQ, policy, how-to. Separated by commas**), **Sources** and **Language** (**One language, or empty for every language**). Empty tags mean every tag. The agent can only narrow that focus, not widen it.

With no knowledge base yet, the page says **No knowledge bases yet** and **Add a knowledge base, and** the agent **can search it**, with **Add a knowledge base**. With none added to this agent, it says **No knowledge searches yet** and **Choose a knowledge base this agent can search for answers.** A base that holds personal data is marked **holds personal data** and public agents cannot search it. If the list cannot be read, the page says **The knowledge searches could not be read.**
