> I think that's because there's nothing good there
One problem is that Google can't bear to serve you up no results, because potential delicious advertising revenue.
Rather than say there aren't any results, they'll serve up fifteen ads (barely recognisable as such) that match something vaguely similar, ignore a few words in your search term that would have excluded some profitable results, rewrite your search term into something that it feels like you should be searching for, drop the quotes around your phrases to find more pages, or some other infuriating reinterpretation.
So even if there isn't anything good there, it's hard to get a feel for whether the data are sparse or you're just being funnelled to stuff that's more profitable.
