Range Filter

Filters documents with fields that have terms within a certain range. Similar to range query, except that it acts as a filter. Can be placed within queries that accept a filter.

{
    "constant_score" : {
        "filter" : {
            "range" : {
                "age" : {
                    "from" : "10",
                    "to" : "20",
                    "include_lower" : true,
                    "include_upper" : false
                }
            }
        }
    }
}

The range filter top level parameters include:

Name	Description
from	The lower bound. Defaults to start from the first.
to	The upper bound. Defaults to unbounded.
include_lower	Should the first from (if set) be inclusive or not. Defaults to true
include_upper	Should the last to (if set) be inclusive or not. Defaults to true.
gt	Same as setting from to the value, and include_lower to false.
gte	Same as setting from to the value, and include_lower to true.
lt	Same as setting to to the value, and include_upper to false.
lte	Same as setting to to the value, and include_upper to true.

Caching

The result of the filter is automatically cached by default. The _cache can be set to false to turn it off.
