Dmitry Kan commented on LUCENE-1486:
------------------------------------
Can someone give me a hand on this parser (despite the jira is so old)?
We need to have the NOT logic work properly in the boolean sense, that is the
following should work correctly:
a AND NOT b
a AND NOT (b OR c)
a AND NOT ((b OR c) AND (d OR e))
Can anybody guide me here? Is it at all possible to accomplish this with this
original CPQP implementation? I would not be afraid of changing QueryParser.jj
lexical specification, if the task requires it.
> 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...
