> LUCENE-1486
>              Project: Lucene - Java
>           Issue Type: Improvement
>           Components: QueryParser
>     Affects Versions: 2.4
>             Reporter: Mark Harwood
>             Priority: Minor
>              Fix For: 2.4.1

> An extension to the default QueryParser that overrides the parsing  
> of PhraseQueries to allow more complex syntax e.g. wildcards in  
> phrase queries.
>
> The implementation feels a little hacky - this is arguably better  
> handled in QueryParser itself. This works as a proof of concept  
> for much of the query parser syntax. Examples from the Junit test  
> include:
>
> checkMatches("\"j*   smyth~\"", "1,2"); //wildcards and fuzzies  
> are OK in phrases
> checkMatches("\"(jo* -john)  smith\"", "2"); // boolean logic works
> checkMatches("\"jo*  smith\"~2", "1,2,3"); // position logic works.
>
> checkBadQuery("\"jo*  id:1 smith\""); //mixing fields in a phrase  
> is bad
> checkBadQuery("\"jo* \"smith\" \""); //phrases inside phrases is bad
> checkBadQuery("\"jo* [sma TO smZ]\" \""); //range queries inside  
> phrases not supported
>
> Code plus Junit test to follow...
