Check the request handler

In these advanced DSE Search tutorial steps, verify that solrconfig.xml includes a solr_query request handler that is required to run CQL Solr queries.

To run CQL Solr queries, the solrconfig.xml file must include a solr_query request handler. An automatically generated solrconfig.xml file includes this request handler.

Procedure

In a text editor, open the solrconfig.xml file from the solr_tutorial46 directory that you downloaded.

In the text editor, search for "SearchHandler".

You see this location:

 <!-- SearchHandler

       http://wiki.apache.org/solr/SearchHandler

       For processing Search Queries, the primary Request Handler
       provided with Solr is "SearchHandler" It delegates to a sequent
       of SearchComponents (see below) and supports distributed
       queries across multiple shards
    -->

Verify that the following request handler appears below the SearchHandler comment.
```
<requestHandler name="solr_query" class="com.datastax.bdp.search.solr.handler.component.CqlSearchHandler"/>
```
If the solr_query request handler is not in the solrconfig.xml file, add it.
