Ahmet Arslan commented on LUCENE-1486:
--------------------------------------

I agree with [~nikhil500], This fix is all about accidentally forgotten thing 
to an already committed code. Also I am not sure why this issue is reopened. 
Any feeling towards a separate issue would be a better fit for this?

> Wildcards, ORs etc inside Phrase queries

> 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...
