TERM Facets with Ordering

TERM Facets with Ordering

Allow to control the ordering of the terms facets, to be ordered by count, term, reverse_count or reverse_term. The default is count.

Here is an example:

POST Method:

http://localhost:9200/mobiles/_search?pretty=true

{
    "query": {
        "query_string": {
            "query": "*a*"
        }
    },
    "facets": {
        "type": {
            "terms": {
                "field": "_type",
 "order" : "term",
                "all_terms": true
            }
        }
    }
}

Results:

{
  "took": 2,
  "timed_out": false,
  "_shards": {
    "total": 1,
    "successful": 1,
    "failed": 0
  },
  "hits": {
    "total": 5,
    "max_score": 1,
    "hits": [
      {
        "_index": "mobiles",
        "_type": "nokia",
        "_id": "1",
        "_score": 1,
        "_source": {
          "name": "lumia 510"
        }
      },
      {
        "_index": "mobiles",
        "_type": "nokia",
        "_id": "2",
        "_score": 1,
        "_source": {
          "name": "lumia 520"
        }
      },
      {
        "_index": "mobiles",
        "_type": "nokia",
        "_id": "3",
        "_score": 1,
        "_source": {
