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.

Also note that more changes may be coming for 5.0: https://github.com/elastic/elasticsearch/issues/17705

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: https://github.com/elastic/kibana/issues/6879
