Crawl log permissions
As a global or SharePoint admin in Office 365, you can grant users read access to crawl log information for the tenant. The crawl log tracks information about the status of crawled content.
A typical use case is in eDiscovery, where you can grant a security group permission to view the crawl log information for the tenant. The users in the security group can view the crawl log data via the eDiscovery portal to check whether crawled content was successfully added to the search index, or whether indexing failed because of an error.
Grant users permission to view the crawl log information
Sign in to https://admin.microsoft.com as a global or SharePoint admin. (If you see a message that you don't have permission to access the page, you don't have Office 365 administrator permissions in your organization.)
In the left pane, under Admin centers, select SharePoint. (You might need to select Show all to see the list of admin centers.) If this opens the new SharePoint admin center, select Classic SharePoint admin center in the left pane.
In the left pane, select search.
On the search administration page, choose Crawl Log Permissions.
In the Crawl Log Permissions box, enter names or email addresses. The names of valid users or user groups are shown in the list as you type letters in the box.
