Range query
editRange query
editReturns documents that contain terms within a provided range.
Example request
editThe following search returns documents where the age field contains a term
between 10 and 20.
GET /_search
{
"query": {
"range" : {
"age" : {
"gte" : 10,
"lte" : 20,
"boost" : 2.0
}
}
}
}
Top-level parameters for range
edit-
<field> -
(Required, object) Field you wish to search.
Parameters for <field>
edit-
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
datevalues in the query.By default, Elasticsearch uses the date
formatprovided in the<field>'s mapping. This value overrides that mapping format.For valid syntax, see
format.If a
formatanddatevalue are incomplete, Elasticsearch replaces any missing year, month, or date component with the start of Unix time, which is January 1st, 1970.For example, if the
formatvalue isdd, Elasticsearch converts agtevalue of10to1970-01-10T00:00:00.000Z.
-
relation -
(Optional, string) Indicates how the range query matches values for
rangefields. 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) Coordinated Universal Time (UTC) offset or IANA time zone used to convert
datevalues in the query to UTC.Valid values are ISO 8601 UTC offsets, such as
+01:00or -08:00, and IANA time zone IDs, such asAmerica/Los_Angeles.For an example query using the
time_zoneparameter, see Time zone inrangequeries.The
time_zoneparameter does not affect the date math value ofnow.nowis always the current system time in UTC.However, the
time_zoneparameter does convert dates calculated usingnowand date math rounding. For example, thetime_zoneparameter will convert a value ofnow/d. -
boost -
(Optional, float) Floating point number used to decrease or increase the relevance scores of a query. Defaults to
1.0.You can use the
boostparameter 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 between0and1.0decreases the relevance score. A value greater than1.0increases the relevance score.
Notes
editUsing the range query with text and keyword fields
editRange queries on text or keyword files will not be executed if
search.allow_expensive_queries is set to false.
Using the range query with date fields
editWhen the <field> parameter is a date field datatype, you can use
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.
GET /_search
{
"query": {
"range" : {
"timestamp" : {
"gte" : "now-1d/d",
"lt" : "now/d"
}
}
}
}
Date math and rounding
editElasticsearch rounds 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||/Mrounds up to2014-12-01T00:00:00.000, excluding the entire month of November. -
gte -
Rounds down to the first millisecond.
For example,
2014-11-18||/Mrounds down to2014-11-01T00:00:00.000, including the entire month. -
lt -
Rounds down to the last millisecond before the rounded value.
For example,
2014-11-18||/Mrounds down to2014-10-31T23:59:59.999, excluding the entire month of November. -
lte -
Rounds up to the latest millisecond in the rounding interval.
For example,
2014-11-18||/Mrounds up to2014-11-30T23:59:59.999, including the entire month.
Example query using time_zone parameter
editYou can use the time_zone parameter to convert date values to UTC using a
UTC offset. For example:
