If you apply this to the terms you're generating, it'll work for any
field.  It will generate a lot of terms for larger fields though,
but you probably don't want to store positional information for them so
it shouldn't be too bad.

Richard had a patch for something like this, but I can't seem to find
any trace of it now.

You'll need to if you also want to match unwildcarded terms on the
same field.

Patching the QueryParser class would be the best way I think.
