We are finishing up building a fresh SharePoint 2016 on-premise solution. Everything is working except search, which seems completely broken.
As far as we can tell all service account permissions are correct for search, but we can never get any results.
The crawling is successful, all of the websites get hit, but nothing ever comes out of the search regardless of the search term.
The only thing I can think is some obscure permissions issue or even though the websites are getting crawled their content is not getting indexed and is somehow unavailable for the most basic search or search itself is just wired up incorrectly.
I loaded up the ULS Viewer and poked around and two things jumped out. The query seems to be going in, it just never has any results.
"Microsoft.Office.Server.Search.Query.Ims.ImsQueryInternal : Number of tables in Result: 4, Relevant Results: 0 (Total: 0, Total including duplicates: 0), Refinement Results: 0"
How can I verify there is any searchable content after a crawl? Also I now have 2 Search Service Applications and am not entirely sure how to wire these up to the different search boxes.
Any advice is greatly appreciated.
