我有一个带有过滤器的多级聚合,我得到了没有匹配过滤器的桶的空结果。我想要消除那些桶。
我尝试指定
文档+查询
GET test/_search
{
"query": {
"match_all": {}
},
"size": 0,
"aggs": {
"type": {
"terms": {
"field": "type.keyword",
"size": 10
},
"aggs": {
"languages": {
"filter": {
"term": {
"sub_type.keyword": "fdsfsd"
}
},
"aggs": {
"sub_type": {
"terms": {
"field": "sub_type.keyword",
"min_doc_count": 1
"size": 10
}
}
}
}
}
}
}
}
响应:
"buckets": [
{
"key": "language",
"doc_count": 1,
"languages": {
"doc_count": 0,
"sub_type": {
"doc_count_error_upper_bound": 0,
"sum_other_doc_count": 0,
"buckets": []
}
}
}

试一试
GET test/_search
{
"query": {
"match_all": {}
},
"size": 0,
"aggs": {
"type": {
"terms": {
"field": "type.keyword",
"min_doc_count": 1,
"size": 10
},
"aggs": {
"languages": {
"filter": {
"term": {
"sub_type.keyword": "fdsfsd"
}
},
"aggs": {
"sub_type": {
"terms": {
"field": "sub_type.keyword",
"min_doc_count": 1,
"size": 10
}
}
}
}
}
}
}
}

在顶级聚合时指定 min_doc_count 。
