Re: Keyword search with space and wildcard

[Brian Campbell]

Basically, yes, I am trying to put a wildcard in a phrase.  My field (a 
Keyword) is the name of a project.  It can be 40 characters long (I'm 
basically indexing some database columns).  Since it is a Keyword and not a 
Text field, it doesn't get tokenized (I do this on purpose) and must match 
up exactly.  I would like for users to be able to search on partial phrases 
such as "Hello w*" and match up to "Hello world" and "Hello washington", 
etc.  Is this not possible?  Is it documented anywhere?

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
