For as much as I love the terminal UI, I don't think the next quantum leap in search functionality can be delivered with it. Assume you have access to an index that is objective / transparent and serves you a (typically) long list of results. The next step is really to make sense and work with the results: you need to quickly and easily filter, order, search within, group or classify or do other bulk operations with all the returned items. Just like with other "information firehose" environments, like social media feeds, email clients etc, its the "meta search" powers that matter and those are probably better served with GUI's.
