Keyword search with space and wildcard

[Brian Campbell <be...@hotmail.com>]

I've created and index that has a Keyword field in it.  I'm trying to do a 
search on that field where my term has a space and the wildcard character in 
it.  For example, I'll issue the following search:  project_name:"Hello w*". 
  I have an entry in the project_name field of "Hello world".  I would 
expect to get a hit on this but I don't.  Is this not the way Lucene 
behaves? Am I doing something wrong?  Thanks.

-Brian

If I understand your issue correctly, I think what you're experiencing is
the fact that you can have a phrase query "hello world", or a wildcard query
+hell* +wor*, but you can't mix the two together.  As far as I've found,
that's a basic limitation you just have to live with.  (Of course, if
someone on the list can show me where I'm wrong, I'll be delighted.)  You
can add boosting to any kind of term (such as wor*^10 or "world order"^10),
but (I don't think) you can't mix wildcards and phrases.

HTH,

Terry

Brian,

This seems akin to the Phrase Searching problem that I encountered (haven't
heard anything back from my posting yet) - which goes as follows:  I try to
do the phrase search "center* form" but the system seems to simply ignore
the wildcard (throws it away) when processing the search - so I get only
results for "center form".  My guess is the parser is processing your search
simply as if it were "hello w".

I've got no solution - was hoping to hear something from the list.

Joe
