Ruby 思考Sphinx-使用或的属性过滤器的多个条件

我有我的搜索方法，如下所示：

class Machine < ActiveRecord::Base
  def filter_search(params, order_query = 'machines.updated_at desc')
      ts_query = ''
      attribute_filters = { order: order_query.gsub(/.*?\./, ''),
                            conditions: {},
                            with: {},
                            limit: 50000,
                            max_matches: Machine::MAX_TS_MATCHES
                          }

      # ... more methods dismissed      

      if params[:currency].present?
        with_null_currency = "*, IF(currency_attr = #{params[:currency]} OR currency_attr = 0, 1, 0) as my_currency"
        attribute_filters[:select] = with_null_currency
        attribute_filters[:with][:my_currency] = 1
      end

      if params[:machine_ad_type_rent] == 'rent' && params[:machine_ad_type_sale].blank?
        with_rent_ad_mask = "*, IF(ad_mask_attr = 1 OR ad_mask_attr = 3, 1, 0) as my_rent_ad_mask"
        attribute_filters[:select] = with_rent_ad_mask
        attribute_filters[:with][:my_rent_ad_mask] = 1
      end

      ids = Machine.search_for_ids(Riddle::Query.escape(ts_query), attribute_filters)
      machines = machines.where(id: ids).order(order_query)
  end
end

但如果我尝试通过这两个参数进行搜索，它将失败：
