Not to be pesky (note by the time it took me to rediscover this, I am not nagging
I wonder, would it perhaps be possible to limit the search engine so that it does a more narrow search by default. Say a maximum number of topics or a restricted list of results in any one burst? Control the engine itself, instead of relying on the users not to mess up?
I wouldn't mind having to run multiple searches, perhaps changing the range slightly each time until I found what I was looking for. Having none, though, it is quite a sizable site to find things on.
