来自官方的Range Query查询介绍【全英文】
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
:
{
"range" : {
"age" : {
"gte" : 10,
"lte" : 20,
"boost" : 2.0
}
}
}
The range
query accepts the following parameters:
|
Greater-than or equal to |
|
Greater-than |
|
Less-than or equal to |
|
Less-than |
|
Sets the boost value of the query, defaults to |
Ranges on date fieldsedit
When running range
queries on fields of type date
, ranges can be specified using the section called “Date Mathedit”::
{
"range" : {
"date" : {
"gte" : "now-1d/d",
"lt" : "now/d"
}
}
}
Date math and roundingedit
When using date math to round dates to the nearest day, month, hour, etc, the rounded dates depend on whether the ends of the ranges are inclusive or exclusive.
Rounding up moves to the last millisecond of the rounding scope, and rounding down to the first millisecond of the rounding scope. For example:
|
Greater than the date rounded up: |
|
Greater than or equal to the date rounded down: |
|
Less than the date rounded down: |
|
Less than or equal to the date rounded up: |
Date format in range queriesedit
Formatted dates will be parsed using the format
specified on the date
field by default, but it can be overridden by passing the format
parameter to the range
query:
{
"range" : {
"born" : {
"gte": "01/01/2012",
"lte": "2013",
"format": "dd/MM/yyyy||yyyy"
}
}
}
Time zone in range queriesedit
Dates can be converted from another timezone to UTC either by specifying the time zone in the date value itself (if the format
accepts it), or it can be specified as the time_zone
parameter:
{
"range" : {
"timestamp" : {
"gte": "2015-01-01 00:00:00",
"lte": "now",
"time_zone": "+01:00"
}
}
}
This date will be converted to |
