I will send you my address to send me some money too.
Seriously, if someone searches for 3 hours and finds something it's just and fair to have a bit of an advantage on an item that is found, over someone that didn't search at all. If time equates to money, as the saying goes, then so be it. That's my half cent....
As to the original topic Frank is probably right. Most folks don't discuss the intricate techniques they use. Basically searching on key words and narrowing it down with ebay's tools is what most folks proabably do. There aren't nearly as many unseen bargains as there were 7-9 yrs ago....
