Mark Miller commented on LUCENE-1486:
-------------------------------------
My first thought is, if we can address some of the issues brought up, there is
no reason to keep this out of core IMHO.
My second thought is, I have a feeling a lot of this concern stems from the
fact that these guys (or one of them) has to duplicate this thing with the
QueryParser code in contrib. That could be reason enough to move it to contrib.
But it doesn't solve the issue longer term when the old QueryParser is removed.
It would need to be replaced then, or dropped from contrib.
With the new info from Mark H, how hard would it be to create a new imp for the
new parser that did a lot of this, in a more defined way? It seems you
basically just want to be able to use multiterm queries and group/or things,
right? We could even relax a little if we have to. This hasn't been released,
so there is still a lot of wiggle room I think. But there does have to be a
resolution with this and the new parser at some point either way.

>
>
> 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...
