Abstract:
1. A method for mapping a plurality of characters in a string, wherein the string comprises a combination of characters representing indexed expressions and a combination of characters representing non-indexed expressions, wherein the method comprises: generating a set of special weights for a plurality of characters representing a plurality of indexed and non-indexed expressions, wherein the order of the special weights are based on an order of the plurality of characters representing the plurality of indexed and non-indexed expressions; if a specific group of characters within the string represent a specific non-indexed expression, associating a weight value of an indexed expression with the specific group of characters representing the specific non-indexed expression; retrieving a plurality of special weights associated with the specific group of characters representing the specific non-indexed expression; and generating a weight array, wherein the weight array comprises the associated weight value of the indexed expression and the plurality of special weights associated with the specific group of characters representing the specific non-indexed expression.
