Luis Alves updated LUCENE-1486:
-------------------------------
Attachment: junit_complex_phrase_qp_07_22_2009.patch
I added 2 testcases that return doc 3, but do not make much sense just to prove
the point that we need more docs describing the use case for complex phrase qp,
and define what is the subset of the supported syntax we want to support.
checkMatches("\"(goos~0.5 AND (mike OR smith) AND NOT ( percival AND
john) ) vacation\"~3","3"); // proximity with fuzzy, OR, AND, NOT
checkMatches("\"(goos~0.5 AND (mike OR smith) AND ( percival AND john)
) vacation\"~3","3"); // proximity with fuzzy, OR, AND
> Wildcards, ORs etc inside Phrase queries

> 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...
