Broken search in Sharepoint, how to fix it?

Question

SharePoint

Good day, in 2013 the search died, and for no apparent reason and logs, when you request any dock or text, it says that there are no results. How to be where to drip?

Answer 1

Try to make Unprovision and Provision through Powershell for the search service, collect the index and do a full crawl of the content, it should help, if it doesn’t help, check the service accounts for the search service, if it doesn’t help again, you will have to recreate the search service. Still there is such a thing as resources search services need min. 4 GB of memory for all GCDs + database load, with a large amount of content, processing can reach > 12 GB + DB, see what you can sit through.
