yearFilter.setSourceModel(model);
nameFilter.setSourceModel(&yearFilter);
view.setSource(&nameFilter);

//....


void onTextChange(int index, QString ntext)
{
    switch(index)
    {
        case yearColumn:
            yearFilter.setFilterRegExp(QRegExp(ntext, Qt::CaseInsensitive));
            break;
        case nameColum:
            namefilter.setFilterRegExp(QRegExp(ntext, Qt::CaseInsensitive));
            break;    
    }
}
