edismax bq, ignore tf/idf?

[Ryan McKinley]

Hi-

I am trying to add a setting that will boost results based on
existence in different buckets.  Using edismax, I added the bq
parameter:

location:A^5 location:B^3

I want this to put everything in location A above everything in
location B.  This mostly works, BUT depending on the number of matches
for each location, location:B can get a higher final score.

Is there a way to ignore tf/idf when boosting this location?

location from a field type:
 class="solr.StrField"  omitNorms="true"


Thanks for any pointers!
