我正在使用Django restframework和 Elasticsearch 来开发移动应用程序的后端应用程序。我需要开发一个时间轴API，以加载该用户正在关注的其他用户的帖子时间轴。以及他们关注的人可能发表的其他相关帖子。

像这样

@some_vf
def someview(req, **kw):
    query = {
        "_source": ["field1", "field2", "field3"],
        "query": {
            "must": [
                {"term": {"username": "zhangsan"}}
            ],
            "should": [
                {"term": {"userid": 1}},
                {"term": {"followed": "something"}}  # other filter with zhangsan
            ]
        },
        "sort": [{"timestamp": {"order": "asc"}}],
        "size": size,
        "from": from_
    }
    es = Elasticsearch()
    data = elasticsearch.helpers.scan(es, ["user_docs_index", "related_posts_index", "followed_some_index"], "_doc")
    # or do your serializers
    return Response(data)
