我有一个问题，一旦我在要聚合的一个字段上添加了一个过滤器，存储桶就为空。第一个查询使我的聚合工作已满，而下面的第二个查询（向下滚动）则没有。我不明白为什么？怎么了？
获取装满的水桶

答案 0 :(得分：0)
根据您的汇总，company是一个嵌套字段，因此您的过滤条件还必须利用nested查询：
{
"query": {
"bool": {
"filter": [
{
"bool": {
"must": [
{
"nested": { <-- use nested here
"path": "company",
"query": {
"bool": {
"must": [
{
"term": {
"company.country_id": 9
}
},
{
"term": {
"company.company_branches.country_id": 9
}
}
]
}
}
}
},
{
"term": {
"active": true
}
},
{
"term": {
"completed": true
}
}
]
}
}
]
}
},
