Documentum 16.4 sorting basic search

HowardMB

I am looking to sort the basic search by object_name, similarly to how it can be done with the advanced search by extending to AdvSearchEx using:

    protected IDfQueryBuilder buildQuery() throws Exception {          

        IDfQueryBuilder queryBuilder=super.buildQuery();

        queryBuilder.addOrderByAttribute("object_name",true);

        return queryBuilder;

   }

What would need to be done to achieve something similar. Should I be modifying SearchEx or Search60 and what method needs to be modified (i.e. do I need to modify the initial search or the dataprovider)?

Any pointers would be appreciated.
