Elasticsearch DSL，在值列表中过滤对象列表

Question

我的数据是这样的：

[
    {
        "id": "00f0bbe514dcaf262c8a",
        "status": "CL",
        "type": "opportunity",
        "locations": [
            {
                "name": "New York, USA",
                "lat": 99.0853,
                "lng": 99.7818,
                "id": "456",
                "type": "CI"
            },
            {
                "name": "Boston, USA",
                "lat": 80.0853,
                "lng": 80.7818,
                "id": "555",
                "type": "CI"
            },
            {
                "name": "London, UK",
                "lat": 10.0853,
                "lng": 10.7818,
                "id": "999",
                "type": "CI"
            }
        ]
    },
    {
        "id": "sadl9asod01",
        "status": "CL",
        "type": "opportunity",
        "locations": [
            {
                "name": "Boston, USA",
                "lat": 80.0853,
                "lng": 80.7818,
                "id": "555",
                "type": "CI"
            },
        ]
    },
    {
        "id": "13094ulk",
        "status": "CL",
        "type": "project",  # has right location but not type
        "locations": [
            {
                "name": "Boston, USA",
                "lat": 80.0853,
                "lng": 80.7818,
                "id": "555",
                "type": "CI"
            },
        ]
    }

]

我想建立一个类型必须是机会的查询：

type_q = ElasticQ('bool', must=[ElasticQ('match', type='opportunity')])
query = self.index.search().query(type_q)

我知道如何使用 dsl 构建“in”查询，例如：

excluded_ids = self._excluded_jobs() # list
query = query.exclude('terms', id=excluded_ids)

但是，我怎样才能将 SQL 中的内容添加到查询中？我会这样做：

WHERE type='opportunity' 
AND 
location.id in (1, 2, 3)

location 表示文档位置数组中的此处对象

类似于：

type_q = ElasticQ('bool', must=[
  ElasticQ('match', type='opportunity'),
  ElasticQ('terms', id=excluded_ids),
])

或者，如果您确实想排除那些 ID：

type_q = ElasticQ('bool', 
                  must=[ElasticQ('match', type='opportunity')]
                  must_not=[ElasticQ('terms', id=excluded_ids)]
)
