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:

• from: The lower bound. Defaults to start from the first.
• to: The upper bound. Defaults to unbounded.
• include_lower: Should the first from (if set) be inclusive or not. Defaults to true.
• include_upper: Should the last to (if set) be inclusive or not. Defaults to true.
• gt: Same as setting from to the value, and include_lower to false.
• gte: Same as setting from to the value,and include_lower to true.
• lt: Same as setting to to the value, and include_upper to false.
• lte: Same as setting to to the value, and include_upper to true.
• boost: Sets the boost value of the query. Defaults to 1.0.
