I need help in SharePoint Online search configuration.
I have one site collection with 2500 subsites and each subsite has many documents. There are more than 1,000,000 documents,So, it's not possible to update property for each and every document based on sub site name.
Now, what I want to do is, If I search using SharePoint sub site name, then, it should also list all the documents under particular sub site.
Kindly let me know, if this is doable or not or any other ideas to achieve this.
