Elasticsearch two level sort in aggregation list - search

Question

Currently I am sorting aggregations by document score, so most relevant items come first in aggregation list like below:
{
'aggs' : {
'guilds' : {
'terms' : {
'field' : 'guilds.title.original',
'order' : [{'max_score' : 'desc'}],
'aggs' : {
'max_score' : {
'script' : 'doc.score'
}
}
}
}
}
}
I want to add another sort option to the order terms order array in my JSON. but when I do that like this :
{
'order' : [{'max_score' : 'desc'}, {"_count" : "desc"},
}
The second sort does not work. For example when all of the scores are equal it then should sort based on query but it does not work.

Answer 1

As a correction to Andrei's answer ... to order aggregations by multiple criteria, you MUST create an array as shown in Terms Aggregation: Order and you MUST be using ElasticSearch 1.5 or later.
So, for Andrei's answer, the correction is:
"order" : [ { "max_score": "desc" }, { "_count": "desc" } ]
As Andrei has it, ES will not complain but it will ONLY use the last item listed in the "order" element.

Answer 2

I don't know how your 'aggs' is even working because I tried it and I had parsing errors in three places: "order" is not allowed to have that array structure, your second "aggs" should be placed outside the first "terms" aggs and, finally, the "max_score" aggs should have had a "max" type of "aggs". In my case, to make it work (and it does actually order properly), it should look like this:
"aggs": {
"guilds": {
"terms": {
"field": "guilds.title.original",
"order": {
"max_score": "desc",
"_count": "desc"
}
},
"aggs": {
"max_score": {
"max": {
"script": "doc.score"
}
}
}
}
}
