Mark Miller commented on LUCENE-1486:
-------------------------------------
bq. I think contrib would be a good place for now, until it gets more stable
and better documented.
If Mark H thinks it should be moved, I won't disagree. But I still don't see a
convincing reason. It could use some more documentation, but so could quite a
few other classes in core. Its something of a subjective call, and more
importantly, it can be addressed now.
I'm not yet convinced its unstable - the only major issue I see so far is the
exception issue - but that wouldn't seem to prompt a move to contrib, but an
update to address the concern. Moving to contrib is always an option, but I
don't think its the default move based on whats been brought up. The standard
move would be to address whatever issues are brought up ... so far I am just
seeing the exception issue as a large one, and I think that is fairly easily
addressable.

> Key: LUCENE-1486
> 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 Harwood
> Priority: Minor
> Fix For: 2.9
>
> Attachments: ComplexPhraseQueryParser.java,
> junit_complex_phrase_qp_07_21_2009.patch, 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...
