python - elasticsearch —获取正确的查询字符串

Question

我是Elasticsearch的新手，目前正在对query_string结果进行距离查询:这是我的代码:

doc = {
        "query": {
            "query_string": {
                "query": term,
                "fields": ['name', 'business_name', 'email', 'city',
                   'state', 'zip_code', 'business_keywords', 'phone_number',
                   'address', 'country'
                ], 
            }, 
            "filter": {
                "geo_distance": {
                    "distance": radius, 
                    "distance_unit": "km", 
                    "distance_type": "arc", 
                    "location": {
                        "lat": latitude, 
                        "lon": longitude
                    }
                }
            }
        }
    }
search_response = client.search(index="b",body=doc)

但我收到以下错误:

RequestError:TransportError(400，u'search_phase_execution_exception'，您无法解析搜索源。期望的字段名称，但是得到了[START_OBJECT]')
任何的想法 ？？

您需要将query_string和geo_distance查询合并为bool查询。

doc = {
        "query": {
          "bool": {
            "must": {
              "query_string": {
                "query": term,
                "fields": ['name', 'business_name', 'email', 'city',
                   'state', 'zip_code', 'business_keywords', 'phone_number',
                   'address', 'country'
                ], 
              }
            }, 
            "filter": {
                "geo_distance": {
                    "distance": radius, 
                    "distance_unit": "km", 
                    "distance_type": "arc", 
                    "location": {
                        "lat": latitude, 
                        "lon": longitude
                    }
                }
            }
        }
    }
