User look-up is a user data query tool provided by the system. You can select conditions the same way as in Behavioral cohorts to precisely search for users and view their data.
Click a user ID in the search results list, or click a user ID on the user list page, to go to the user's Behavior sequence page and view the user's current properties and tags and recent behavior sequence.
You can also click the icon in the top right corner or press ctrl/cmd + K to quickly search for a single account ID or distinct ID.
