我的查询有效。它根据Id聚合数据,并根据创建的字段查找 MOST RECENT 对象。我遇到的问题是我想找到最近的第二次而不是最近的。我该怎么做?我一直在查看文档,我所能找到的是范围对我没什么帮助。谢谢:))
{
"query":{
"match": {
"name": "Robert"
}
},
"aggs": {
"previous": {
"terms": {
"field": "Id",
"order": {"timeCreated": "desc"}
},
"aggs": {
"timeCreated": {
"max": {"field": "created"}
}
}
}
}
}

Top_hits
正是您要找的。使用此:
{
"query":{
"match": {
"name": "A"
}
},
"aggs": {
"previous": {
"terms": {
"field": "Id"
},
"aggs": {
"latestRecords": {
"top_hits": {
"sort": {
"created": {
"order": "desc"
}
},
"size" :2
}
}
}
}
}
}
