Mark Miller commented on LUCENE-1486:
-------------------------------------

Hey Mark, this doesn't work correctly with the new constant score mode. I'm 
hesitant to put something in core that only works with boolean expansion.

I'm not sure what needs to be done (I started and realized my interest wasn't 
high enough). Could you update this? Otherwise I'm tempted to push off to 3.0...

Unless another brave soul steps of course. Or I may jump back in - my brain is 
fickle.

>                 URL: https://issues.apache.org/jira/browse/LUCENE-1486
>             Project: Lucene - Java
>          Issue Type: Improvement
>          Components: QueryParser
>    Affects Versions: 2.4
>            Reporter: Mark Harwood
>            Assignee: Mark Miller
>            Priority: Minor
>             Fix For: 2.9

>         Attachments: ComplexPhraseQueryParser.java, LUCENE-1486.patch, 
> TestComplexPhraseQuery.java
>
>
> 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...
