== 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`
[float]
=== Date options
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 `gte` to `2012-01-01T00:00:00+01:00` with `"time_zone":"+10:00"` will still use `+01:00` time zone.
When applied on `date` fields the `range` query accepts also a `format` parameter.
The `format` parameter will help support another date format than the one defined in mapping:
[source,js]
--------------------------------------------------
{
"range" : {
"born" : {
"gte": "01/01/2012",
"lte": "2013",
"format": "dd/MM/yyyy||yyyy"
}
}
}
--------------------------------------------------
