更新到elasticsearch 2.3后无法找到嵌套的geopoint

Question

我们使用AWS管理的Elasticsearch服务,最近从1.5升级到2.3.我们在python中使用elasticsearch-dsl包来构建我们的查询并设法迁移我们的大多数查询,但无论我尝试什么,geo_distance都会被破坏.

制图:

{
        'company': {
            'properties': {
                'id': {'type': 'integer'},
                'company_number': {'type': 'string'},
                'addresses': {
                    'type': 'nested',
                    'properties': {
                        'postcode': {'type': 'string', 'index': 'not_analyzed'},
                        'location': {'type': 'geo_point'}
                    }
                }
             }
        }
} 

Python代码使用elasticsearch-dsl == 0.0.11

            test_location = '53.5411062377, -2.11485504709'
            test_distance = "3miles"
            location_filter = F("geo_distance", 
                                location=test_location,
                                distance=test_distance)
            query = query.filter("nested", 
                                 path="addresses",
                                 filter=location_filter)

库生成的查询:

{'query': {'filtered': {'filter': {'nested': {'filter': {'geo_distance': {'distance': u'3miles', 'location': '53.5411062377, -2.11485504709'}}, 'path': 'addresses'}}, 'query': {'match_all': {}}}}}

我们使用相同的映射在新的2.3上创建了一个全新的索引.

更新到elasticsearch-dsl == 2.1.0并尝试将过滤器转换为查询后:

geo_query = Q({"bool": {
                    "must": [
                        {
                            "geo_distance": {
                                "distance": "test_distance",
                                "addresses__location": test_location,
                            }
                        },
                    ]
                }})

这会生成以下查询:

{'query': {'bool': {'must': [{'geo_distance': {'distance': '3 miles', u'addresses.location': {'lat': '53.5411062377', 'lon': '-2.11485504709'}}}]}}}

我们得到以下异常:

RequestError: TransportError(400, u'search_phase_execution_exception', u'failed to find geo_point field [addresses.location]')

我尝试将该字段引用为"location","addresses.location","addresses"并使用旧的嵌套查询类型.我无法弄清楚映射是否在2.3中不再有效,或者我是否构造错误的查询.

查询

Q({'nested': {'filter': {
                        'geo_distance': {'distance': u'3miles', 'location': '53.5411062377, -2.11485504709'}
                    },
                    'path': 'addresses.location'}})

生成以下错误:

RequestError: TransportError(400, u'search_phase_execution_exception', u'[nested] nested object under path [addresses.location] is not of nested type')

我想我需要将lat_lon:True添加到地理坐标查询的映射中才能工作,但没有一个例子有它.

非常感谢任何帮助,谢谢!

这应该有效：

        test_location = '53.5411062377, -2.11485504709'
        test_distance = "3miles"
        location_query = Q("geo_distance", 
                            addresses__location=test_location,
                            distance=test_distance)
        query = query.filter("nested", 
                             path="addresses",
                             query=location_query)
