I have great admiration for Jade's persistence in continuing to use ranked search. As I have said many times, I abandoned ranked search many years ago because the ranking algorithm seems so completely irrational. So I really don't understand how anybody finds anything with ranked search.
The question of ranked search vs. exact search for the most part is not a New Search vs. and Old Search issue. Well, when New Search first came out it had such a strong bias towards ranked search that it made using exact search problematical. That situation eventually improved a great deal, plus there are now some really neat exact search features in New Search that were not in Old Search. But many of the time and place issues that Jade is describing bedevil exact search just as much as ranked search.
