The first thing to do is to use QSortFilterProxy as a middleman. The problem is that QSortFilterProxy will only search top level tree nodes. The way to implement custom filters is to subclass QSortFilterProxy and reimplement filterAcceptsRow(). But I couldn't figure out any way to quickly access sub elements using QModelIndex, nor could I find anything on the 'net.
