我正在尝试对聚合数据运行后置过滤器,但它无法正常工作。有人可以查看我的查询,并建议我在这里做错了什么。
"query" : {
"bool" : {
"must" : {
"range" : {
"versionDate" : {
"from" : null,
"to" : "2016-04-22T23:13:50.000Z",
"include_lower" : false,
"include_upper" : true
}
}
}
}
},
"aggregations" : {
"associations" : {
"terms" : {
"field" : "association.id",
"size" : 0,
"order" : {
"_term" : "asc"
}
},
"aggregations" : {
"top" : {
"top_hits" : {
"from" : 0,
"size" : 1,
"_source" : {
"includes" : [ ],
"excludes" : [ ]
},
"sort" : [ {
"versionDate" : {
"order" : "desc"
}
} ]
}
},
"disabledDate" : {
"filter" : {
"missing" : {
"field" : "disabledDate"
}
}
}
}
}
}
}
查询中的步骤:
答案 0 :(得分:0)
post_filter
的目的是在计算聚合后运行。因此,post_filter
对聚合结果没有任何影响。
您可以执行的操作是应用顶级filter
aggregation,以便在汇总时不考虑没有disabledDate
的文档,即只考虑与>的文档strong> disabledDate
。
