Subject RE: Query: A ? B

Otis:

Maybe I don't understand this right, but I *think* I am looking for
something different:

I am trying to write a query like this: "my * house" which should match "my
own house", "my red house", "my small house", but should not match "my
house" ... you get the idea.

If I am not mistaken, a wildcard query only works if the wildcard is within
a word (or token), and it would allow me to do things like "g*" matching
"green", "great", ...etc. I don't know how to make that work for multi words
scenarios.

Here is what I tried WildcardQuery in the unit test (TestBasics):

Query query = new WildcardQuery(new Term("field","six hundred * five"));

Thanks!
Jochen
