Subject [jira] Updated: (LUCENE-2002) Add oal.util.Version ctor to QueryParser
Date Wed, 21 Oct 2009 20:58:59 GMT

Michael McCandless updated LUCENE-2002:
---------------------------------------

    Attachment: LUCENE-2002-29.patch

Attached patch, for 2.9..x

I added required Version param to QueryParser, MultiFieldQueryParser
and ComplexPhraseQueryParser (contrib), which enable position
increments when matchVersion >= LUCENE_19.

For the deprecated ctors it defaults to Version.LUCENE_24 for back
compat.

Unfortunately, JavaCC generates two public ctors for QueryParser (one taking
CharStream, another taking QueryParserTokenManager) that I don't know
how to override to take a Version param.

> This is a followup of LUCENE-1987:
> If somebody uses StandardAnalyzer with Version.LUCENE_CURRENT and then uses QueryParser,
phrase queries will not work, because the StopFilter enables position Increments for stop
words, but QueryParser ignores them per default. The user has to explicitely enable them.
> This issue would add a ctor taking the Version constant and automatically enable this
setting. The same applies to the contrib queryparser. Eventually also StopAnalyzer should
add this version ctor.
> To be able to remove the default ctor for 3.0 (to remove a possible trap for users of
QueryParser), it must be deprecated and the new one also added to 2.9.1.
