Hi Team
I thought this was simple, but I am just missing something here. Any guidance
would be very appreciated.
What have I done so far:
1. I have created a custom querParser (class SamplePluggin extends
QParserPlugin { ), which right now does nothing but logs an info message, and
returns a new LuceneQParser() instance with the same parameters.
2. I am on solr 7.5 and I have added the path to the jar and referenced
the plugin in the following ways in my solrconfig.xml:
<lib path="/Users/aroopganguly/libs/test-plugins-aroop-all.jar" />
<queryParser name="sampleparser"
class="com.aroop.plugins.SamplePluggin"/>
Now when I create a collection with this solrconfig, I keep getting this
exception stack:
I have tried debugging the live solr instance and for the life of me, I cannot
understand why am I getting this cast exception
