订单弹性搜索聚合

Question

我的 "query" 中有多个聚合，请参阅示例。有时我会使用更多聚合。我喜欢对聚合本身进行排序，因此 "brand" 始终位于聚合列表的顶部（在结果中）然后 "energy" 例如？

如果我自己尝试解决但找不到任何有用的方法。

{
    "size": 1000,
    "_source": ["id"],
    "query": { 
        "bool": { 
            "must": [
                { "match": { "category_default": "2" }}
            ],
            "must_not": [
                { "match": { "category_default": "2196" }},
                { "match": { "leverbaarheid_id": "3" }}
            ]
        }
    },  
    "aggs": {
        "brand": {
            "terms": {
                "field": "brand.keyword",
                "order": { "_term": "asc" }
            }
        },
        "min_price": { "min": { "field" : "selling_price" } },
        "max_price": { "max": { "field" : "selling_price" } },
        "energy": {
            "terms": {
                "field": "energy.keyword",
                "order": { "_term": "asc" }
            }
        }
    }
}

Answer 1

我不认为这是直接可能的。

I like to order the aggregations itself so "brand" is always on top of the aggregations list (in the result) and then "energy" for example?

这里使用name it "aggregations list"虽然它实际上是一个JSON对象，也就是Elasticsearch aggregations:

的输出格式

Each aggregation is associated with a logical name that the user defines ... . These logical names will also be used to uniquely identify the aggregations in the response.

此外，在 JSON 对象中，键可以按任何顺序排列，例如参见 [=13=]。

您必须根据您的聚合创建一个列表，并在客户端正确排序。
