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:

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:

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 2014-12-31T23:00:00 UTC.
	now is not affected by the time_zone parameter (dates must be stored as UTC).
