status of "?" wildcard queries in rc5

[DM...@lbl.gov]

I've searched the mail archive and I'm still a bit confused as to the
current status of "?" wildcard queries.  My experience, using
lucene-1.2-RC5, is that "?" wildcard queries are unsupported using the
StandardAnalyzer or SimpleAnalyzer.

For example, the following search on two fields (go_id and go_desc)
(using StandardAnalyzer for indexing and searching):

%java Search ./index "+go_id:5737 +go_desc:biosynthesis"
Result:
go_id:4853, 6783, 5737
go_desc:uroporphyrinogen decarboxylase, heme biosynthesis, cytoplasm
Score: 1.0

using "*" wildcard:
%java Search ./index "+go_id:5737 +go_desc:biosynth*sis"
Result:
go_id:4853, 6783, 5737
go_desc:uroporphyrinogen decarboxylase, heme biosynthesis, cytoplasm
Score: 1.0

using "?" wildcard:
%java Search ./index "+go_id:5737 +go_desc:biosynth?sis"
Noresults

Is this the expected behavior for RC5, a reported bug, or an unreported bug?

thanks,

David,

As far as I can tell the '?' character works as it should with
WildcardQuery.  See
src/test/org/apache/lucene/search/TestWildcard.java.
The tests there use SimpleAnalyzer and WildcardQuery directly (i.e. not
QueryParser).  All tests pass.  Try comparing your code with the code
in the above test class.
