我是Elasticsearch的新手,并且一直在使用它的高级休息客户端来执行日期范围的聚合。当我运行代码时,查询会成功执行,但返回的对象的null为聚合值:
这就是我的尝试:
POST /index_name/1234/_search?size=0
{
"aggs": {
"range": {
"date_range": {
"field": "date_created",
"format": "MM",
"ranges": [
{ "from": "now-0M/M" }
]
}
}
}
}
searchResponse对象将聚合作为空值。
但是当我在Kibana中运行聚合查询时,这就是我得到的
{
"took": 1,
"timed_out": false,
"_shards": {
"total": 5,
"successful": 5,
"skipped": 0,
"failed": 0
},
"hits": {
"total": 2,
"max_score": 0,
"hits": []
},
"aggregations": {
"range": {
"buckets": [
{
"key": "11-*",
"from": 1509494400000,
"from_as_string": "11",
"doc_count": 2
}
]
}
}
}
输出:
"hits": [
{
"_index": "index_name",
"_type": "1234",
"_id": "AV__ZmN6KNpjod2Y_7PE",
"_score": 1,
"_source": {
"category": 1234,
"i_id": 87665,
"v_Id": 12,
"date_created": "2017-11-27T14:33:38.954Z"
}
},
{
"_index": "index_name",
"_type": "1234",
"_id": "AV_-XzlpzSX1UeitwVjd",
"_score": 1,
"_source": {
"category": 1234,
"i_id": 8766,
"v_Id": 2,
"date_created": "2017-11-27T09:46:00.095Z"
}
}
]
有人可以帮我这个吗?我有点困难了。
根据请求添加样本数据:
{{1}}
谢谢!
答案 0 :(得分:0)
最后,我找到了问题的答案。创建聚合对象后,我们必须手动将其设置为SearchRequest。
Stream -> Stream Object
添加了修复代码的行:
.each(console.log)
