我的文档如下:
{
{
"Task_Id": 3,
"Subject": "Abhishek1"
}
{
"Task_Id": 3,
"Subject": "Abhishek2"
}
{
"Task_Id": 2,
"Subject": "Abhishe3"
}
}
当我搜索主题时,我想要唯一的Task_Id。
我应用了以下查询:
curl -XGET "localhost:9200/clouddemo/_search?pretty" -H "Content-Type: application/json" -d"{\"_source\":[\"Subject\",\"Task_Id\"],\"query\": {\"query_string\" : {\"default_field\" : \"Subject\",\"query\" : \"Abhi\"}},\"aggs\" : {\"distinct_id\" : {\"cardinality\" : {\"field\" : \"Task_Id\"}}}}" (For the windows)
问题:这只是针对不同的计数,但我想要不同的计数。
预期产出:
{
"Task_Id": 3,
"Subject": "Abhishek2"
}
{
"Task_Id": 2,
"Subject": "Abhishe3"
}(only this two object not count)
