Solr - How to set a default operator in Solr 6.6?

Question

In Solr 6.6 the defaultOperator config setting has been deprecated in managed-schema

 <solrQueryParser defaultOperator="OR"/>

Where should I set it in Solr 6.6?

Omura

use "q.op" query parameter while requesting to solr. if default operator is set to AND and if you mention OR with q.op. The "q.op" request parameter takes precedence. – Peristalsis

Answer 1

As for vinod suggestion, that parameter can be used at query time with q.op=OR, and if you, like me, prefer to have it predefined you can add the value in solrconfig.xml itself, in the /select requestHandler

In the same file is possible to specify also a <defaultSearchField> (also deprecated and removed) with the df parameter

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="df">text_en</str>
        <str name="q.op">OR</str>
    </lst>
</requestHandler>
