Hello SharePointers,
Yesterday I faced an issue with SharePoint 2013 search. I retrieved logs and found an error message as w3wp.exe – all query processing components are in ‘failed’ status.

Error

SharePoint 2013 search has encountered a problem that prevents results from being returned. If the issue persists, please contact your administrator.

Correlation ID:

The correlation ID for an issue is – 790b329e-391e-2001-cdad-4e0d6da3b38c

The first thing we noticed on the server is that the C:\ drive is almost full. that means there was no disk space on the server. So I went ahead and clear some space by deleting unwanted files from the disk.

I went ahead an retrieved logs and found an error with w3wp process.

w3wp.exe

All query processing components are in ‘failed’ status

Solution.

While checking the search service application, I saw a warning icon for the index partition and searchable items “All Errors”.

So we now got an exact error which is causing search results to load. I also know the solution of this issue.

To resolve this issue, we need to Reset the search Index.

Please Note: Reset Index will remove the content index stored, So we need to run the full crawl to rebuild the index once all search components are stored healthy.

Reset Index will take few minutes. The next steps should be restart the search services.

  • SharePoint server Search
  • SharePoint Search Host Controller

Now, this will turn all search components Healthy/green.

All Query Processing Components Are in 'Failed' Status

Now the last thing, just go ahead and perform a Search Operation on SharePoint site. This will so us the SharePoint search results.

Now the last step, Just go ahead and perform a FULL CRAWL on content sources. Once Full crawls completes it will display search results.
