| <section><p><a class="xref" href="Lucene.Net.QueryParsers.Classic.QueryParser.html">QueryParser</a> which permits complex phrase query syntax eg "(john jon |
| jonathan~) peters*". |
| <p> |
| Performs potentially multiple passes over Query text to parse any nested |
| logic in PhraseQueries. - First pass takes any PhraseQuery content between |
| quotes and stores for subsequent pass. All other query content is parsed as |
| normal - Second pass parses any stored PhraseQuery content, checking all |
| embedded clauses are referring to the same field and therefore can be |
| rewritten as Span queries. All PhraseQuery clauses are expressed as |
| ComplexPhraseQuery objects |
| </p> |
| <p> |
| This could arguably be done in one pass using a new <a class="xref" href="Lucene.Net.QueryParsers.Classic.QueryParser.html">QueryParser</a> but here I am |
| working within the constraints of the existing parser as a base class. This |
| currently simply feeds all phrase content through an analyzer to select |
| phrase terms - any "special" syntax such as * ~ * etc are not given special |
| status |
| </p></p> |
