"sort":[
{
"creationTime":{
"order":"asc"
}

            "query": "field:hello world"
        }
    },
    "aggs": {
        "group_by_userId": {
            "terms": {
                "field": "userId",

            }
        }
    },
    "sort": [
        {
            "creationTime": {
                "order": "asc"
            }
        }
    ]
}'

分组聚合查询

curl -X GET "192.1.1.1:9200/service-2025-01/_search" -H 'Content-Type: application/json' -d'
{
"_source": ["timestamp","field1","field2","lost","userId"],
"size": 10,
"query": {
"bool": {
"must": [
{
"term": {
"field1": "hello"
}
},
{
"term": {
"field2": "world"
}
}
]
}
},
"aggs": {
"average_per_5_seconds": {
"date_histogram": {
"field": "timestamp",
"fixed_interval": "5s",
"min_doc_count": 0
},
"aggs": {
