This is a follow up to
KULRICE-6766. I didn't really have a chance to implement a proper test for this method since it's going to take a bit of work (not difficult, just a bit meticulous). Basically, whoever does this will need to simulate the creation of ResultRow objects and their associated Columns which are returned from a document search by the KNS. And then test the various aspects of DocumentSearchResultSetConfiguration which has a few different things it can do.
