Как правильно искать несколько моделей в SunSpot Solr?

Модель профиля

has_one :match

searchable do
  string        :country
  string        :state
  string        :city
end

Модель спички

belongs_to :profile

searchable do
  string :looking_for_education
  integer :age_from
  integer :age_to
end

ProfilesController # Index

def index

  @search = Sunspot.search Profile, Match do

    with(:country, params[:country])
    with(:state,   params[:state])      
    with(:looking_for_education, params[:looking_for_education])
