Potential feature request?

[Oliver Hummel <hu...@informatik.uni-mannheim.de>]

Hi,

I just stumbled across an issue with Lucene's QueryParser. Perhaps you already
discussed this here, but googling for it didn't bring me to a solution.

I realized that lucene is obviously not able to exclude fields, right? E.g.
something like

  -url:com

always delivers 0 results. Is this behaviour deliberate? Is there any rationale
for it?

Would it be possible to include such a feature, since it currently breaks the
use of the MultiFieldQueryParser as soon as a query with an exclude is entered.
Or would it at least be possible to modifiy the MFQP that applies excludes
somehow only for the content field?

Thanks in advance for any comments.

Best,

  Oliver

Ok, RTFM... :-)

http://lucene.apache.org/java/docs/queryparsersyntax.html
says that one exclude alone always delivers 0 results. Hm, I thought I tried it
with multiple terms, but obviously something went wrong. Everything seems to work.

Sorry, if I caused any confusion.

Best,

  Oliver
