Class XmlQParserPlugin

java.lang.Object

org.apache.solr.search.QParserPlugin

org.apache.solr.search.XmlQParserPlugin

All Implemented Interfaces:

SolrInfoBean, NamedListInitializedPlugin

public class XmlQParserPlugin
extends QParserPlugin

The XmlQParserPlugin extends the QParserPlugin and supports the creation of queries from XML.

Example:

<BooleanQuery fieldName="description">
   <Clause occurs="must">
      <TermQuery>shirt</TermQuery>
   </Clause>
   <Clause occurs="mustnot">
      <TermQuery>plain</TermQuery>
   </Clause>
   <Clause occurs="should">
      <TermQuery>cotton</TermQuery>
   </Clause>
   <Clause occurs="must">
      <BooleanQuery fieldName="size">
         <Clause occurs="should">
            <TermsQuery>S M L</TermsQuery>
         </Clause>
      </BooleanQuery>
   </Clause>
</BooleanQuery>

You can configure your own custom query builders for additional XML elements. The custom builders need to extend the SolrQueryBuilder or the SolrSpanQueryBuilder class.

Example solrconfig.xml snippet:

<queryParser name="xmlparser" class="XmlQParserPlugin">
  <str name="MyCustomQuery">com.mycompany.solr.search.MyCustomQueryBuilder</str>
</queryParser>
