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:

{
    "range" : {
        "age" : {
            "from" : 10,
            "to" : 20,
            "include_lower" : true,
            "include_upper": false,
            "boost" : 2.0
        }
    }
}

The range query top level parameters include:

Name	Description
from	The lower bound. Defaults to start from the first.

gte	Same as setting from to the value,and include_lower to true.
