Well I imagine that searches probably follow a Pareto 80/20 rule to some extent. In other words, 80% of searches are on 20% of total topics. So the hypothetical group would focus on those high volume search topics first.
I also imagine the things I search most rarely may be the most pressing compared to the ones I do all the time (as an individual, the things I search most often, I probably know where to go to find the info directly -- API docs and such).
