Description

Lucene includes a query parser that is able to create the full-spectrum of Lucene queries, using an XML data structure.

This patch adds "xml" query parser support to Solr.

Example (from lucene/queryparser/src/test/org/apache/lucene/queryparser/xml/NestedBooleanQuery.xml):

<BooleanQuery fieldName="contents">  
  <Clause occurs="should">
    <BooleanQuery fieldName="contents">
      <Clause occurs="must">
        <TermQuery>doesNotExistButShouldBeOKBecauseOtherClauseExists</TermQuery>
      </Clause>
    </BooleanQuery>
  </Clause>
  <Clause occurs="should">
    <TermQuery>bank</TermQuery>
  </Clause>
</BooleanQuery>
