json - Elasticsearch 嵌套过滤器

Question

这是由Elastic Search API返回的文档结构:
{ "process_name":"process01", "beat": { "hostname":"12345","name":"blablabla" }, }
通过process_name进行过滤很容易，但是如何通过嵌套在beat中的host_name进行过滤呢？

尝试失败1

{ "size":10000, "query" : { "bool" : { "should": [ { "match" : { "process_name" : "process01" } }, { "match" : { "process_name" : "process02" } } ], "must": [ { "match" : { beat: { "hostname":"12345" } } } ] } } }
错误消息1:

(failed to deserialize object type=class com.logshero.api.SearchApiRequest):

尝试失败2

{ "size":10000, "query" : { "bool" : { "should": [ { "match" : { "process_name" : "process01" } }, { "match" : { "process_name" : "process02" } } ], "must": [ { "match" : { "hostname":"12345" } } ] } } }
错误消息2:

{"hits":{"total":0,"max_score":null,"hits":[]}}

Answer 1

您可以使用以下查询。您还必须确保将映射中的节拍定义为嵌套类型。

{
    "size": 10000,
    "query": {
        "bool": {
            "should": [{
                "match": {
                    "process_name": "process01"
                }
            }, {
                "match": {
                    "process_name": "process02"
                }
            }],
            "must": [{
                "match": {
                    "beat.hostname": "12345"
                }
            }]
        }
    }
}

谢谢
