Description

I have taken latest version of Portal and solr-web plugins from 5.2.x branches.

I have Solr 1.3.

Performed all the required steps to make solr work based on information available at various sources in community.

Everything was setup fine and I can do seach in solr admin interface for liferay content.

I can also do search in Control Panel.

Issue was coming in Search Portlet. Anything I search was resulting in NPE like from all OpenSearchImpl. Only directory search was resulting the content.

So search portlet is not working when configured with solr.

I have done debugging to find out root cause of this issue and found that NPE is being thrown from class.

portal-kernel/src/com/liferay/portal/kernel/search/HitsImpl.java

In that class there is method

public String snippet(int n)

{ return _snippets[n]; }

But in my case _snippet is Null , so it throws NPE. I have small content in each of my blog , wiki and web content i.e "Test this feature" , I not sure why snippet is coming as null.

So I have modified above function like

public String snippet(int n) {
if(_snippets == null)

{ return null; }

return _snippets[n];
}

After doing this change and redeploying portal NPE Gone and it worked like charm.

This should solve the problem of NPE.
