                    is not specified in a document.

                * cases - A dict that translates source field values
                    to custom values.
                * default - An optional default value to use if the

        :type rank_expression: string
        :param rank_expression: The expression to evaluate for ranking
            or thresholding while processing a search request. The
            RankExpression syntax is based on JavaScript expressions
            and supports:

            * Integer, floating point, hex and octal literals
            * Shortcut evaluation of logical operators such that an
                expression a || b evaluates to the value a if a is
                true without evaluting b at all
            * JavaScript order of precedence for operators
            * Arithmetic operators: + - * / %
            * Boolean operators (including the ternary operator)
            * Bitwise operators
            * Comparison operators
            * Common mathematic functions: abs ceil erf exp floor
                lgamma ln log2 log10 max min sqrt pow
            * Trigonometric library functions: acosh acos asinh asin
                atanh atan cosh cos sinh sin tanh tan
            * Random generation of a number between 0 and 1: rand
            * Current time in epoch: time
            * The min max functions that operate on a variable argument list

            Intermediate results are calculated as double precision
            floating point values. The final return value of a
            RankExpression is automatically converted from floating
            point to a 32-bit unsigned integer by rounding to the
            nearest integer, with a natural floor of 0 and a ceiling
            of max(uint32_t), 4294967295. Mathematical errors such as
            dividing by 0 will fail during evaluation and return a
            value of 0.

            The source data for a RankExpression can be the name of an
            IndexField of type uint, another RankExpression or the
            reserved name text_relevance. The text_relevance source is
            defined to return an integer from 0 to 1000 (inclusive) to
            indicate how relevant a document is to the search request,
            taking into account repetition of search terms in the
            document and proximity of search terms to each other in
            each matching IndexField in the document.

            customize ranking, see the Amazon CloudSearch Developer
            Guide.
