我有一個工作的elasticsearch查詢,但我無法弄清楚如何使用java API解析返回值。看起來無論我怎樣配置它,我都會遇到空值。Elasticsearch中的聚合解析
查詢在elastisearch是:
GET user_profile/active_time/_search
{
"size" : 0,
"aggregations" : {
"agg1" : {
"filter" : {
"range" : {
"timestamp" : {
"from" : 0,
"to" : 1501786179177,
"include_lower" : true,
"include_upper" : true
}
}
},
"aggregations" : {
"agg2" : {
"terms" : {
"field" : "userId",
"size" : 0
}
}
}
}
}
}
它產生的返回值:
{
"took": 2,
"timed_out": false,
"_shards": {
"total": 5,
"successful": 5,
"failed": 0
},
"hits": {
"total": 55,
"max_score": 0,
"hits": []
},
"aggregations": {
"agg1": {
"doc_count": 55,
"agg2": {
"doc_count_error_upper_bound": 0,
"sum_other_doc_count": 0,
"buckets": [
{
"key": 0,
"doc_count": 34
},
{
"key": 295,
"doc_count": 12
},
{
"key": 59,
"doc_count": 3
},
{
"key": 764,
"doc_count": 3
},
{
"key": 788,
"doc_count": 3
}
]
}
}
}
}
我不知道如何正確地得到桶出來聚集2.在以前的迭代中,我能夠使用來訪問它
Terms terms = sr.getProperty("agg2");
但過濾器在那種情況下不起作用。我應該重新格式化我的查詢還是有一些方法來解析這個?謝謝。
