[[query-dsl-range-query]]
=== Range query
++++
<titleabbrev>Range</titleabbrev>
++++

Returns documents that contain terms within a provided range.

[[range-query-ex-request]]
==== Example request

The following search returns documents where the `age` field contains a term
between `10` and `20`.

[source,console]
----
GET /_search
{
  "query": {
    "range": {
      "age": {
        "gte": 10,
        "lte": 20,
        "boost": 2.0
      }
    }
  }
}

[[range-query-top-level-params]]
==== Top-level parameters for `range`

`<field>`::
+
--
(Required, object) Field you wish to search.
--

[[range-query-field-params]]
==== Parameters for `<field>`

`gt`::
(Optional) Greater than.

`gte`::
(Optional) Greater than or equal to.

`lt`::
(Optional) Less than.

`lte`::
(Optional) Less than or equal to.

`format`::
+
--
(Optional, string) Date format used to convert `date` values in the query.

By default, {es} uses the <<mapping-date-format,date `format`>> provided in the
`<field>`'s mapping. This value overrides that mapping format.

For valid syntax, see <<mapping-date-format,`format`>>.

WARNING: If a format or date value is incomplete, the range query replaces any
missing components with default values. See <<missing-date-components>>.

--

[[querying-range-fields]]
`relation`::
+
--
(Optional, string) Indicates how the range query matches values for `range`
fields. Valid values are:

`INTERSECTS` (Default)::
Matches documents with a range field value that intersects the query's range.

`CONTAINS`::
Matches documents with a range field value that entirely contains the query's range.

`WITHIN`::
Matches documents with a range field value entirely within the query's range.
--

`time_zone`::
+
--
(Optional, string)
{wikipedia}/List_of_UTC_time_offsets[Coordinated Universal
Time (UTC) offset] or
{wikipedia}/List_of_tz_database_time_zones[IANA time zone]
used to convert `date` values in the query to UTC.

Valid values are ISO 8601 UTC offsets, such as `+01:00` or -`08:00`, and IANA
time zone IDs, such as `America/Los_Angeles`.

For an example query using the `time_zone` parameter, see
<<range-query-time-zone,Time zone in `range` queries>>.

[NOTE]
====
The `time_zone` parameter does **not** affect the <<date-math,date math>> value
of `now`. `now` is always the current system time in UTC.

However, the `time_zone` parameter does convert dates calculated using `now` and
<<date-math,date math rounding>>. For example, the `time_zone` parameter will
convert a value of `now/d`.
====
--

`boost`::
+
--
(Optional, float) Floating point number used to decrease or increase the
<<relevance-scores,relevance scores>> of a query. Defaults to `1.0`.

You can use the `boost` parameter to adjust relevance scores for searches
containing two or more queries.

Boost values are relative to the default value of `1.0`. A boost value between
`0` and `1.0` decreases the relevance score. A value greater than `1.0`
increases the relevance score.

[[range-query-notes]]
==== Notes

[[ranges-on-text-and-keyword]]
===== Using the `range` query with `text` and `keyword` fields
Range queries on <<text, `text`>> or <<keyword, `keyword`>> fields will not be executed if
<<query-dsl-allow-expensive-queries, `search.allow_expensive_queries`>> is set to false.

[[ranges-on-dates]]
===== Using the `range` query with `date` fields

When the `<field>` parameter is a <<date,`date`>> field data type, you can use
<<date-math,date math>> with the following parameters:

* `gt`
* `gte`
* `lt`
* `lte`

For example, the following search returns documents where the `timestamp` field
contains a date between today and yesterday.

[source,console]
----
GET /_search
{
  "query": {
    "range": {
      "timestamp": {
        "gte": "now-1d/d",
        "lt": "now/d"
      }
    }
  }
}
----

[[missing-date-components]]
====== Missing date components

For range queries and <<search-aggregations-bucket-daterange-aggregation,date
range>> aggregations, {es} replaces missing date components with the following
values. Missing year components are not replaced.

[source,text]
----
MONTH_OF_YEAR:    01
DAY_OF_MONTH:     01
HOUR_OF_DAY:      23
MINUTE_OF_HOUR:   59
SECOND_OF_MINUTE: 59
NANO_OF_SECOND:   999_999_999
----

For example, if the format is `yyyy-MM`, {es} converts a `gt` value of `2099-12`
to `2099-12-01T23:59:59.999_999_999Z`. This date uses the provided year (`2099`)
and month (`12`) but uses the default day (`01`), hour (`23`), minute (`59`),
second (`59`), and nanosecond (`999_999_999`).

[[range-query-date-math-rounding]]
====== Date math and rounding
{es} rounds <<date-math,date math>> values in parameters as follows:

`gt`::
+
--
Rounds up to the first millisecond not covered by the rounded date.

For example, `2014-11-18||/M` rounds up to `2014-12-01T00:00:00.000`, excluding
the entire month of November.
--

`gte`::
+
--
Rounds down to the first millisecond.

For example, `2014-11-18||/M` rounds down to `2014-11-01T00:00:00.000`, including
the entire month.
--

`lt`::
+
--
Rounds down to the last millisecond before the rounded value.

For example, `2014-11-18||/M` rounds down to `2014-10-31T23:59:59.999`, excluding
the entire month of November.
--

`lte`::
+
--
Rounds up to the latest millisecond in the rounding interval.

For example, `2014-11-18||/M` rounds up to `2014-11-30T23:59:59.999`, including
the entire month.
--

[[range-query-time-zone]]
===== Example query using `time_zone` parameter

You can use the `time_zone` parameter to convert `date` values to UTC using a
UTC offset. For example:

[source,console]
----
GET /_search
{
  "query": {
    "range": {
      "timestamp": {
        "time_zone": "+01:00",        <1>
        "gte": "2020-01-01T00:00:00", <2>
        "lte": "now"                  <3>
      }
    }
  }
}
----
// TEST[continued]

<1> Indicates that `date` values use a UTC offset of `+01:00`.
<2> With a UTC offset of `+01:00`, {es} converts this date to
`2019-12-31T23:00:00 UTC`.
<3> The `time_zone` parameter does not affect the `now` value.
