how about:
define_index do
..
has "IF(price <= 20, 1, 0)", :as => :under_20, :type => :boolean, :facet =>
true
has "IF(price <= 50 AND price > 20, 1, 0)", :as => :20_to_50, :type =>
:boolean, :facet => true
has "IF(price <= 100 AND price > 50, 1, 0)", :as => :50_to_100, :type =>
:boolean, :facet => true
has "IF(price > 100, 1, 0)", :as => :over_100, :type => :boolean, :facet =>
true
..
end
You can then get 'bucket' counts using a standard facet call.
