Hi Hoss :)
thanks for the feedback - I arrived @ the same conclusion . The biz requirement
is that these *_exact fields match exactly the original contents of the field.
Right now we are using Dismax, and changing this means rewriting a lot of the
queries , which isn't possible.
That's why I was wondering how Dismax breaks it all apart. It makes sense...I
suppose what I'd like to have is a way to tell dismax which fields NOT to
tokenize the input for. For these fields, it would pass the full q instead of
each part of it. Does this make sense? would it be useful at all?

I agree, it makes sense as you say...i must have missed the initial tokens. I
can't confirm atm, so I'll follow the common sense path :)
As usual, thanks for your time and insights :)
