Hi Guys,
Here I want to share the issues which I encountered while
working with the search service application in SharePoint 2013
In this post I am going to deal with these two errors
- Search has encountered a problem that prevents
results from being returned. If the issue persists, please contact your
administrator.
- The search request was unable to connect to the
Search Service.
Error1: Search has
encountered a problem that prevents results from being returned. If the issue
persists, please contact your administrator.
I have configured the service application and created some
content sources and used to get the results as expected. But somehow suddenly I
got this below issue (im not sure on the root cause but expecting this is the
issue with the patching on server)
When I searched in the 15 Hive logs with the above
correlation id, I found this below information saying "Unable to Connect to Index System"
Failed to

I searched on internet and grabbed the info from different
sites and came to know that, the issue the search index partition is degraded.
To resolve
this, we need to reset the index of the search service application and do the
full crawl of the content sources.
In
my case, I have 2 search service applications, so I ran this command to find
which is in degraded state
$ssappn
= Get-SPEnterpriseSearchServiceApplication
Get-SPEnterpriseSearchStatus
–SearchApplication $ssappn[0].Name
and
then
Get-SPEnterpriseSearchStatus
–SearchApplication $ssappn[1].Name
The
second service application given me the status like degraded
So
I went to central admin and then opened
the second search service application (which was degraded) and did the index
reset as shown below( you can find a link in the quick launch called “Index
Reset” in search administration page).
It takes some time. Once it is completed, do a full crawl of
your content source.This
may solves issue in some cases and gives you the results... But in my case I did
not get the results. I encountered the same issue as previous.
So i decided to delete this corrupted search service application (as it is dev enviroment) to avoid issues for my search application (the first one in above)
So i deleted this corrupted second service application and try to perform the search. But this time i got new error
Error 2 : The
search request was unable to connect to the Search Service
Cause
for this is the proxy for search service application doesn’t exist in the farm.
This is responsible for the communication between webpart and the service
application
So to resolve this issue, we need to create a new proxy. Run
these commands to create
$searchServiceApp =
Get-SPEnterpriseSearchServiceApplication
New-SPEnterpriseSearchServiceApplicationProxy
-SearchApplication $searchServiceApp
Now my results appeared like charm :)
Hope this helps..
