=== Range Query

Matches documents with fields that have terms within a certain range.
The type of the Lucene query depends on the field type, for `string`
fields, the `TermRangeQuery`, while for number/date fields, the query is
a `NumericRangeQuery`. The following example returns all documents where
`age` is between `10` and `20`:

[source,js]
--------------------------------------------------
{
    "range" : {
        "age" : {
            "gte" : 10,
            "lte" : 20,
            "boost" : 2.0
        }
    }
}
--------------------------------------------------

The `range` query accepts the following parameters:

[horizontal]
`gte`:: 	Greater-than or equal to
`gt`::  	Greater-than
`lte`:: 	Less-than or equal to
`lt`::  	Less-than
`boost`:: 	Sets the boost value of the query, defaults to `1.0`

coming[1.4.0]

When applied on `date` fields the `range` filter accepts also a `time_zone` parameter.
The `time_zone` parameter will be applied to your input lower and upper bounds and will
move them to UTC time based date:

[source,js]
--------------------------------------------------
{
    "range" : {
        "born" : {
            "gte": "2012-01-01",
            "lte": "now",
            "time_zone": "+1:00"
        }
    }
}
--------------------------------------------------

In the above example, `gte` will be actually moved to `2011-12-31T23:00:00` UTC date.

NOTE: if you give a date with a timezone explicitly defined and use the `time_zone` parameter, `time_zone` will be
ignored. For example, setting `from` to `2012-01-01T00:00:00+01:00` with `"time_zone":"+10:00"` will still use `+01:00` time zone.
