I'll ask you a few questions about things related to Microsoft Search. ※I am currently validating the capabilities of Microsoft Search with an Office 365 E3 license. And, I also use the file sharing connector (Targeted Release).
If a large number of files are uploaded to SharePoint Online etc., may the creation of the index used by Microsoft Search fail? Also, how many files will be uploaded and index creation will fail?
Is it possible to use the KQL search function in Bing search?
