One of the most common reasons why Google Drive documents are missing in Glean is because the document owner has a different email domain than the Google Drive instance domain. By default, Glean only crawls documents owned by users that have the same domain as the Google Drive instance.
Admins can specify the allowed Google Drive domains which Glean can crawl content from in Workspace Settings.
- Navigate to Workspace Settings.
- Under Setup, select Apps.
- Search for and select the Google Drive App.
- In the Setup tab, add the allowed Google Drive domains in Step 4.
- Save the Setup.
Documents from additional allowed domains will appear in Glean after a full content crawl and document processing.
