        Creates a new instance of a search class given it's class name and (optional) arguments to pass to it's setOptions method. If the search method implements OptionHandler and the options parameter is non-null, the search method will have it's options set.
        Parameters:
        searchName - the fully qualified class name of the search class
        options - an array of options suitable for passing to setOptions. May be null.
        Returns:

      • makeCopies

        public static ASSearch[] makeCopies​(ASSearch model,
                                            int num)
                                     throws java.lang.Exception
        Creates copies of the current search scheme. Note that this method now uses Serialization to perform a deep copy, so the search object must be fully Serializable. Any currently built model will now be copied as well.
        Parameters:
        model - an example search scheme to copy
        num - the number of search scheme copies to create.
        Returns:
        an array of search schemes.
        Throws:
        java.lang.Exception - if an error occurs
