docs: Retrieves the subject(lhs expression) which could be an array
  or string, the search(rhs expression) which could be any JmesPath
  expression. If subject is an array, this function returns true if
  one of the elements in the array is equal to the provided search
  value. If the provided subject is a string, this function returns
  true if the string contains the provided search argument.
  
  @param evaluatedArgs List of input expressions
  @return True subject contains search;
  False otherwise
