聚合查询

The aggregations API allows grouping by multiple fields, using  sub-aggregations . Suppose you want to group by fields  field1 ,  field2  and  field3 :

{ "aggs" : { "agg1" : { "terms" : { "field" : "field1" }, "aggs" : { "agg2" : { "terms" : { "field" : "field2" }, "aggs" : { "agg3" : { "terms" : { "field" : "field3" } } } } } } } }

Of course this can go on for as many fields as you'd like.

聚合API允许通过多个域的分组，使用 子聚合 。假设你想组的领域 field1 ， field2 和 field3 ：

{ "aggs" : { "agg1" : { "terms" : { "field" : "field1" }, "aggs" : { "agg2" : { "terms" : { "field" : "field2" }, "aggs" : { "agg3" : { "terms" : { "field" : "field3" } } } } } } } }

当然，这可能会为你会像许多领域。
