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。
