Look only for files while searching document

Question

Hi,

I'm using https://learn.microsoft.com/en-us/graph/api/driveitem-search?view=graph-rest-1.0&tabs=http to search for documents in drive.
This search returns both folders and files.
What is the most optimal way to filter out folders while searching so result only contains files?
I cannot filter after the API has responded as pagination logic is built around items returned in search response
PS. I cannot use Microsoft Search API as it only works for delegated access whereas I'm working on application context

Hi @captain_atharv ,

Based on my research and testing, there is no way to filter out folders while searching, as a workaround ,you can use the following Graph API to look only for files.

https://graph.microsoft.com/v1.0/sites/{site-id}/lists/{list-id}/items?$expand=fields&$filter=fields/ContentType ne 'Folder'
