我正在使用 Python 的 Elasticsearch DSL 包： http ://elasticsearch-dsl.readthedocs.org/en/latest/search_dsl.html

我的示例 elasticsearch 条目如下所示：

{
  "_index" : "users",
  "_type" : "player",
  "_id" : "1",
  "_version" : 5,
  "found" : true,
  "_source":{"doc": {"weight": 92, "height": 184, "gender": "male", "firstname": "John", "lastname": "Smith", "age": 31, "country": "France"}}

我正在尝试获取该firstname = "John*"国家/地区列表中的所有条目[France, Australia]。这是我的代码：

firstname = 'John'
s = Search(index='users').using(elasticsearch)
must = [
  {'match': {'doc.firstname': {'query': firstname + '*', 'boost': 2}}},
  {'terms': {'doc.country': [u'France', u'Australia']}}]

s = s.query(Q('bool', must=must))
response = s.execute()

它返回空结果，我做错了什么？我正在使用这里的建议： Elasticsearch match list against field

我是 Elasticsearch 的新手，仍然对我们在哪里使用查询与过滤器感到困惑。

我为此使用了 should 参数：

firstname = 'John'
s = Search(index='users').using(elasticsearch)
must = [
  {'match': {'doc.firstname': {'query': firstname + '*', 'boost': 2}}}]

should = []
for country in countries:
  should.append({'match': {'doc.country': country}})

s = s.query(Q('bool', must=must, should=should, minimum_should_match=1))
response = s.execute()
