I have installed and configured SOLR 6.6.3 on linux OS. And have configure the DIH and a search handler called filesearch which is having simple shard as locolhost:8983/solr/fI_idx. But there is a problem while searching using that configured search handler. From Admin UI in the query section if run using /select in the request Handler am able to get the result which is indexed in the localserver, but when i try to pass the filesearch as request handler and a search it giving
null:org.apache.solr.common.SolrException:
org.apache.solr.client.solrj.SolrServerException: IOException occured
when talking to server at: http://localhost:8983/solr/FI_idx

ERROR true
Would anyone able to tell me what could be the issue. You might be asking a question why you want new searchHanlder when you have default /select am trying this as part of distributed search functionality.
definition of /filesearch
<requestHandler name="/filesearch" class="solr.SearchHandler">
<lst name="defaults">
<str name="q.alt">*:*</str>
<str name="shards">localhost:8983/solr/FI_idx</str>
<str name="df">document</str>
</lst>
</requestHandler>
The main issue which am observing is because of luceneMatchVersion in oldserver it was LUCENE_40 now i have changed it to LUCENE_CURRENT or 6.6.3 after changing the version i did a indexing using DIH by pulling records from database. Then try to search using filesearch but its not working below is the full error
