I have single server farm SP2013 migrated from 2010 and the crawler is set up to perform a incremental crawl every 15minutes and a full crawl every friday evending.
Some times it hangs up for days and it never finishes:
What could the probelm be? I know that in order to improve the crawl performance the search service should have a dedicated/own server and set up a continuous crawl, but this is not possible for the moment. Obviously, by stopping and restart the SearchService it runs again ...for some weeks.
And what does
Errors exactly mean?
Edit: I had to stop the crawl again, since it did not finish but the successes, warnings and errors do not increment. After a while it restarted a full crawl by itself and I fear the scenario will repeat. For the weekend I'll try to reset the index and start the it again...hoping it works.
Update: I resetted the index and started a full crawl during weekend, it did not finish.
