我有以下查询 - 由grafana生成，当我针对嵌套“buckets”类型的索引运行时，它返回空值。
但是当我将“buckets”字段作为非嵌套类型运行时，当我针对相同的索引运行时，相同的查询返回非零数字
以下是查询：
{
"size": 0,
"query": {
"bool": {
"filter": [{
"range": {
"timestamp": {
"from": "1504818600000",
"to": "1504818780000",
"include_lower": true,
"include_upper": true,
"format": "epoch_millis",
"boost": 1.0
}
}
},
{
"query_string": {
"query": "app_name:ssss AND buckets.name:dddr",
"fields": [],
"use_dis_max": true,
"tie_breaker": 0.0,
"default_operator": "or",

}
}
],
"disable_coord": false,
"adjust_pure_negative": true,
"boost": 1.0
}
},
"aggregations": {
"2": {
"date_histogram": {
"field": "timestamp",
"format": "epoch_millis",
"interval": "1m",
"offset": 0,
"order": {
"_key": "asc"
},
"keyed": false,
"min_doc_count": 0,
"extended_bounds": {
"min": "1504818600000",
"max": "1504818780000"
}
},
"aggregations": {
"1": {
"avg": {
"field": "buckets.basicStats.memUsed"
}
}
}
}
}
}
针对非嵌套类型运行：
{
"took" : 4,
"timed_out" : false,
"_shards" : {
"total" : 5,
"successful" : 5,
"skipped" : 0,
"failed" : 0
},
"hits" : {
"total" : 3,
"max_score" : 0.0,
"hits" : [ ]
},
"aggregations" : {
"2" : {
"buckets" : [
{
"key_as_string" : "1504818600000",
"key" : 1504818600000,
"doc_count" : 1,
"1" : {
"value" : 1.03766064E8
}
},
{
"key_as_string" : "1504818660000",
"key" : 1504818660000,
"doc_count" : 1,
"1" : {
"value" : 1.0376628E8
}
},
{
"key_as_string" : "1504818720000",
"key" : 1504818720000,
"doc_count" : 1,
"1" : {
"value" : 1.0376628E8
}
},
{
"key_as_string" : "1504818780000",
"key" : 1504818780000,
"doc_count" : 0,
"1" : {
"value" : null
}
}
]
}
}
}
但是当针对嵌套类型运行时：
"buckets" : [
{
"key_as_string" : "1504818600000",
"key" : 1504818600000,
"doc_count" : 0,
"1" : {
"value" : null
}
},
{
"key_as_string" : "1504818660000",
"key" : 1504818660000,
"doc_count" : 0,
"1" : {
"value" : null
}
},
{
"key_as_string" : "1504818720000",
"key" : 1504818720000,
"doc_count" : 0,
"1" : {
"value" : null
}
},
{
"key_as_string" : "1504818780000",
"key" : 1504818780000,
"doc_count" : 0,
"1" : {
"value" : null
}
}
]
有没有办法让我更改查询以适用于嵌套类型？

在对嵌套类型进行聚合时，您应该使用嵌套聚合。 Link
使用以下内容替换您的聚合，看看这是否适合您。
"aggregations": {
"nested": {
"nested": {
"path": "buckets"
},
"aggs": {
"1": {
"avg": {
"field": "buckets.basicStats.memUsed"
}
}
}
}
}
