Today I’ll talk about an error which may occur with search on-premise.
When you have a lot a document and not a big farm, the crawl can take a long time, but sometimes it takes a looooooooooooooooooooooong time without any result!
Something like this
As you see in this crawl log, it has been more than 16 hours without nothing (no errors, no successes, nothing…)
If that happens to you, I would suggest those 3 simple steps
Go to the content source and stop all crawl
Open services and reset SPSearchHostController Service.
Warning : Doing this will cause an short interruption of the search in your farm, some user can experience a “Something went wrong” message if they perform a search shortly after the reset. Do this during planified maintenance hour if the search is already in use.
Go to the content source and start all crawl
After that, you should get some result in the crawl log
Hoping this helps
