Update include+exclude syntax for Terms/Significant terms aggs

[ycombinator]

The syntax for include and exclude has changed for terms and significant_terms aggregations in Elasticsearch 2.0. In Elasticsearch 1.x, it was possible to have a terms/significant_terms aggregation request that looked like this:

  "significant_terms": {
    "field": "machine.os.raw",
    "size": 10,
    "include": {
      "pattern": ".*sport.*", 
      "flags": "CASE_INSENSITIVE"
    }
  }

Starting with Elasticsearch 2.0, this is no longer allowed. Specifically, it is not possible to specify flags anymore. The new syntax looks like this:

  "significant_terms": {
    "field": "machine.os.raw",
    "size": 10,
    "include": ".*sport.*"
  }

• 1.x syntax: https://www.elastic.co/guide/en/elasticsearch/reference/1.7/search-aggregations-bucket-terms-aggregation.html#_filtering_values
• 2.x syntax: https://www.elastic.co/guide/en/elasticsearch/reference/2.0/search-aggregations-bucket-terms-aggregation.html#_filtering_values_2

Observed

Sense (with Elasticsearch 2.x) will autocomplete to the 1.x syntax.

Expected

Sense (with Elasticsearch 2.x) should autocomplete to the 2.x syntax.

Thanks @skearns64. Now that Sense has moved into the Kibana repo as Console starting with 5.0, I'm tracking any ES 5.0 impacts on Console here: elastic/kibana#6879
