> 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}}):
> {code}
> <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>
> {code}
