  • Where does this error appear? Can you provide us with more detailed event viewer details and ULS log details in your question? It is possible you'll need to increase the log level for the search component to see what's going on with the search.

Please try to reset Index in search service application, and restart all SharePoint search services in "Manage services on server".

After the above, start a full crawl for your content source, compare the result.
