Has anyone EVER found what he or she was looking for using a search engine on a specific site? E.g. if you want to find out a list of apple prices from 1980 onward, don't you dare search for "apple prices" at the BLS website. And just now I was trying to find the academic homepage of Robert Balling, a climate scientist at Arizona State University. I tried at first to go through the hoops of "Academics" and then different departments, but that wasn't working. In desperation I tried searching the site for "balling." Ha ha why would that work?
In all honesty, has anyone EVER found the desired information using a site-specific engine? I think I'm about 0 for 50 in such searches. I usually don't even bother anymore.
