The above will sort the countries buckets based on the average height among the female population.
coming[1.4.0]
Multiple criteria can be used to order the buckets by providing an array of order criteria such as the following:
[source,js]
--------------------------------------------------
{
"aggs" : {
"countries" : {
"terms" : {
"field" : "address.country",
"order" : [ { "females>height_stats.avg" : "desc" }, { "_count" : "desc" } ]
},
"aggs" : {
"females" : {
"filter" : { "term" : { "gender" : { "female" }}},
"aggs" : {
"height_stats" : { "stats" : { "field" : "height" }}
}
}
}
}
}
}
--------------------------------------------------
The above will sort the countries buckets based on the average height among the female population and then by
their `doc_count` in descending order.
NOTE: In the event that two buckets share the same values for all order criteria the bucket's term value is used as a
tie-breaker in ascending alphabetical order to prevent non-deterministic ordering of buckets.
==== Minimum document count
It is possible to only return terms that match more than a configured number of hits using the `min_doc_count` option:
