performance - 如何在Elasticsearch和Python中初始化标签数组列表

Question

我想在下面初始化一个空数组。我怎样才能做到这一点 ？

"hits": {
        "total": 1,
        "max_score": 1,
        "hits": [
            {
                "_index": "customers",
                "_type": "customer",
                "_id": "QOTzXMUcrnbsYyFKeouHnjlkjQB3",
                "_score": 1,
                "_source": {
                    "uid": "QOTzXMUcrnbsYyFKeouHnjlkjQB3",
                    "email": "george@gmail.com",
                    "favorites": [],  < ---- this is the problem
                    "history": [],
                    "settings": {},
                    "purchases ": [],
                    "created": 1507892081201,
                    "updated": 1507892081201
                }
            }
        ]
    }

不知道我的问题是否正确，但是如前所述，如果要避免空数组中的[]值，您可以简单地使用null值，以便搜索和索引这些null值。请引用null values elasticsearch的官方文档。
