KQL - Search all documents docx and xls in a specific team

Hi,

I need to use KQL language for advanced search in Teams and want to limit the scope to a team.

Here my query

path:"https://afpa365.sharepoint.com/sites/TheDigitalInterneTeam/Documents partages" filetype:docx filetype:xls

What i don't understand is with few libraries the query works and sometimes it's not working.
Look at the screenshoots

> For this team (demo) it's working perfectly

> but for this team (i have 84 files on it), i have this error. I have tried with no filters first.

I don't understand why i have this error. At first, i was thinking it was a permission issue but it seems not. Do  you have an idea ?

Thanks
