Taleau AND/OR Parser

I need someone to code me a Tableau calculated field that will receive a Parameter (P1) as input. P1 will be a string with the following format: "[string1] [operator1] [string2] [operator2] [string3] [operator3] [string4] [operator4] [string5]" [string] can be any string [operator] can be any, and only one, of AND/AND NOT/OR P1 Example: ABCD OR BCDE AND DE AND NOT CDE The calculated field should be built based on CONTAIN clause, which means that, for every calculation, the algorithm should allways read: CONTAINS [string] AND/AND NOT/OR CONTAINS [string].... The calculaiton result should be an integer: 1 if the current record is TRUE for the calculation 0 if the current record is FALSE for the calculation -1 if P1 doesnt comply to the desired P1 format
