How to exclude fields in a SOLR query - Stack Overflow

Unfortunately the ability to remove a field name via the query string is still an outstanding improvement request. Please see SOLR-3191 for more details.

Until this improvement is implemented, you will need to specify all 19 fields in the fl parameter. However, you could update your default /select requestHandler to define the 19 fields that you want to return as a default setting that would be applied to all queries unless it was overridden in the query string.

Here is a modified version of the default /select requestHandler from the example solrconfig.xml:

  <requestHandler name="/select" class="solr.SearchHandler">      <!-- default values for query parameters can be specified, these       will be overridden by parameters in the request       -->      <lst name="defaults">        <str name="echoParams">explicit</str>        <int name="rows">10</int>        <str name="df">text</str>        <!-- Only showing 3 fields for this example -->        <str name="fl">field1,field2,field3</str>      </lst>    </requestHandler>  

For more details about these default settings and requestHandler configuration, please refer to RequestHandlers and SearchComponents in SolrConfig.
