`POST /v1/raiz/knowledge/search`

Find the passages that best answer `q` in the organization's searchable documents, best first. `agentId` searches exactly what that Agent can find; `knowledgeDocumentIds` limits the search to those documents. Paused, deleted and not-yet-indexed documents are never searched. Read a whole document with `get_knowledge_document` and `expand=content`.

- **Scopes:** any one of `raiz:knowledge:read`, `raiz:knowledge:write`
- **Credentials:** an API key, a client-credentials token or a person's access token
- **Effect:** read-only; safe to retry
- **Limits:** request body up to 32 KB, response up to 1 MB
- **CLI:** `arbol raiz knowledge search` · **MCP tool:** `raiz_knowledge_search`
