                                           java.util.Map<java.lang.String,Answer> operandMap,

                                           WdkModelException

this function accept a boolean expression that defines the combination of cached answers in current user's history. In the expression answers can be identified by their IDs or names. For example, #1 UNION "ans_gene", where the answer ID starts with #, and answer name can be quoted by double quote (the double quote is required if there's space in answer name). User can use parenthese in the boolean expression to change the order of its execution. For example, #1 MINUS (ans_mRNA UNION "ans tRNA")
