expr

var expr: String?

Defines one or more numeric expressions that can be used to sort results or specify search or filter criteria. You can also specify expressions as return fields.

You specify the expressions in JSON using the form {"EXPRESSIONNAME":"EXPRESSION"}. You can define and use multiple expressions in a search request. For example:

{"expression1":"_score*rating", "expression2":"(1/rank)*year"}

For information about the variables, operators, and functions you can use in expressions, see Writing Expressions in the Amazon CloudSearch Developer Guide.
