Notion
Perform a search over: - "internal": Perform a semantic search over your entire Notion workspace and connected sources (Slack, Google Drive, Github, Jira, Microsoft Teams, Sharepoint, OneDrive, or Linear). - "users": Perform a search over the Notion users in the current workspace. You can use search when you need to find information which is not already available via other tools, and you don't know where it's located. If the user doesn't have access to Notion AI features, the search will automatically fall back to a workspace search that doesn't use AI or include connected sources. This will be indicated by the "type" field in the response being "workspace_search" instead of "ai_search". Do NOT use search to get information about a Database's integrations, views, or other components. If initial results do not contain all the information you need, you can try more specific queries. After obtaining internal search results, if the user asks for the full contents of a page or database, use the "fetch" tool. This tool only shows some details like a highlight and the URL and title of each search result. To find pages under a Notion database, use this tool and supply the database's URL as the data_source_url parameter. These look like "collection://f336d0bc-b841-465b-8045-024475c079dd". You can get this URL by using the "fetch" tool to view the database and copying the URL from the <data-source url="..."> block. Keep in mind that Notion-flavored Markdown has this concept of a hierarchy of <database> blocks that contain <data-source> blocks, but users aren't familiar with the Notion "Data Source" terminology or product. Prefer to refer to both of them as "databases" in your response to humans to avoid confusion. Examples of searches: 1. Search for information across the workspace: { "query": "quarterly revenue report", "query_type": "internal" } 2. Search within a specific page and its children: { "query": "meeting notes action items", "query_type": "internal", "page_url": "https://www.notion.so/workspace/Team-Hub-1234567890abcdef" } 3. Search within a database's pages: { "query": "design review feedback", "query_type": "internal", "data_source_url": "collection://f336d0bc-b841-465b-8045-024475c079dd" } 4. Search within a specific teamspace: { "query": "project updates", "query_type": "internal", "teamspace_id": "f336d0bc-b841-465b-8045-024475c079dd" } 5. Search for users: { "query": "[email protected]", "query_type": "user" } 6. Find users by partial name: { "query": "sarah", "query_type": "user" } Common use cases: - "What does the sales team require from the product team in the next quarter?" - "Find all meeting notes that mention the new pricing strategy" - "Which pages discuss the API migration project?" - "Find all team members with email addresses ending in @design.company.com" - "What are the latest updates on the mobile app redesign?"
