ruby-on-rails - Rails 4 elasticsearch使用多个搜索条件，结合了搜索功能

Question

我正在为项目使用elasticsearch-rails，有一个组合搜索功能，所有列都在一个表中。我只是编写了一个自定义搜索功能，但搜索dsl无效，无法获得任何结果。

def self.combine_search_filter(remark=nil, sim_card_supplier_id=nil, work_mode=nil, operator_status=nil, platform_management_status=nil, online_status=nil, sim_card_set_id=nil, iccid_from=nil, iccid_to=nil, actived_at_from=nil, actived_at_to=nil, check_in_at_from=nil, check_in_at_to=nil, device_mac_from=nil, device_mac_to=nil)
    response = __elasticsearch__.search(
      "size": 1000,
      "query": {
        "filtered": {
          "filter":   {
            "bool": {
              "filter":   [
                { "term":  { "sim_card_supplier_id": sim_card_supplier_id } },
                { "term":  { "work_mode": work_mode } },
                { "term":  { "operator_status": operator_status } },
                { "term":  { "platform_management_status": platform_management_status } },
                { "term":  { "online_status": online_status } },
                { "term":  { "sim_card_set_id": sim_card_supplier_id } }
                { "range": { "iccid": { "from": iccid_from, "to": iccid_to }}},
                { "range": { "check_in_at": { "from": check_in_at_from, "to": check_in_at_to }}},
                { "range": { "actived_at": { "from": actived_at_from, "to": actived_at_to }}},
                { "range": { "device_mac": { "from": device_mac_from, "to": device_mac_to }}}
              ]
            }
          }
        }
      }
    )
end

并且参数可能会通过nil，我该怎么做才能使搜索DSL有效？

我宁愿建议您将searchkick gem用于rails，这样可以使 flex 搜索如此简单，并使搜索更智能，查询也更简单。
