长问题简介：如何在聚合形成的组中进行选择？
有用的细节：我已将1800张照片的EXIF数据编入索引，并使用geohash单元格过滤器（即位置）和日期直方图聚合（即时间）对它们进行分组。
因此，我成功地将在一定距离内彼此接近的照片分组并在特定时间内拍摄。
但现在，我还想在组中选择组（ NOT 单个文档），其中包含字段/值对“Image Software”：“Instagram”。如果我使用过滤器，它将只返回特定文档，而不是组。我可以采取什么方法？
（如果我可以添加另一个条件来在组中进行选择，例如另一个字段/值对，则会更好。
下面的POST返回上述组。我现在想要在包含字段/值对“Image Software”：“Instagram”的组中进行选择并返回这些组。
POST account_index/_search?search_type=count
{
"query": {
"filtered": {
"filter": {
"geohash_cell": {
"location": {
"geohash": "swtcw"
},
"neighbors": true,
"precision": 5
}
}
}
},
"aggs": {
"zamanlar": {
"date_histogram": {
"field": "EXIF DateTimeOriginal",
"interval": "7d"
},
"aggs": {
"grouped": {
"top_hits": {
"size": 10000
}
}
}
}
}
}
以下是因上述POST而返回的众多群组之一的元素示例：

答案 0 :(得分：0)
您应该能够通过将现有聚合包装成filter aggregation这样的方式使其正常工作：
POST account_index/_search?search_type=count
{
"query": {
"filtered": {
"filter": {
"geohash_cell": {
"location": {
"geohash": "swtcw"
},
"neighbors": true,
"precision": 5
}
}
}
},
"aggs": {
"zamanlar": {
"filter": { <------ wrap your aggregation into this new filter aggregation
"term": {
"Image Software": "Instagram"
}
},
"aggs": {
"zamanlar": {
"date_histogram": {
"field": "EXIF DateTimeOriginal",
"interval": "7d"
},
"aggs": {
"grouped": {
"top_hits": {
"size": 10000
}
}
}
}
}
}
}
}
