The Lucene NestedBooleanQuery.xml source code
<?xml version="1.0" encoding="UTF-8"?> <!-- This query was added to demonstrate nested boolean queries - there was a bug in the XML parser which added ALL child <Clause> tags to the top level tags ie. took child and grandchild elements instead of just child elements. This was due to the use of the Element.getElementsByTagName() call in BooleanQueryBuilder --> <BooleanQuery fieldName="contents"> <Clause occurs="should"> <BooleanQuery fieldName="contents"> <Clause occurs="must"> <TermQuery>doesNotExistButShouldBeOKBecauseOtherClauseExists </Clause> </BooleanQuery> </Clause> <Clause occurs="should"> <TermQuery>bank </Clause> </BooleanQuery>
