Aggregations changesedit

Deprecated pattern element of include/exclude for terms aggregations has been removededit

The include and exclude options of terms aggregations used to accept a sub pattern object which has been removed. The pattern should now be directly put as a value of the include and exclude fields. For instance, the below terms aggregation:

POST /twitter/_search?size=0
{
    "aggs" : {
        "top_users" : {
            "terms" : {
                "field" : "user",
                "include": {
                  "pattern": "foo.*"
                },
                "exclude": {
                  "pattern": ".*bar"
                }
            }
        }
    }
}

should be replaced with:

POST /twitter/_search?size=0
{
    "aggs" : {
        "top_users" : {
            "terms" : {
                "field" : "user",
                "include": "foo.*",
                "exclude": ".*bar"
            }
        }
    }
}

Numeric to and from parameters in date_range aggregation are interpreted according to format nowedit

Numeric to and from parameters in date_range aggregations used to always be interpreted as epoch_millis, making other numeric formats like epoch_seconds unusable for numeric input values. Now we interpret these parameters according to the format of the target field. If the format in the mappings is not compatible with the numeric input value, a compatible format (e.g. epoch_millis, epoch_second) must be specified in the date_range aggregation, otherwise an error is thrown.

global_ordinals_hash and global_ordinals_low_cardinality are deprecated in the terms aggregationedit

The execution hints global_ordinals_hash and global_ordinals_low_cardinality are deprecated and should be replaced by global_ordinals which now internally choose whether it should remap global ordinals to dense ordinals or directly use the segment ordinals.

missing is deprecated in the composite aggregationedit

The missing option of the composite aggregation is deprecated, missing_bucket should be used instead.
