1. A method comprising: determining a first mapping between a first file extension and a file kind, and a second mapping between a second file extension and the file kind; storing the first mapping and the second mapping in a mapping database; receiving a particular file uploaded to a content repository of a cloud-based collaboration platform for an enterprise account; identifying a particular file extension associated with the particular file; determining, from the mapping database, a particular file kind to which the particular file extension maps; storing the particular file kind as metadata for the particular file to be used during a given search; responsive to a search request initiated by an administrator of the enterprise account, performing a search based on the file kind for files across users associated with the enterprise account, wherein the files are stored in the content repository of the cloud-based collaboration platform, wherein the search is performed independent of user permission, and wherein results of the search yield content collaborated upon among multiple of the users associated with the enterprise account.
