Ever notice that most sites that provide their own search features tend to suck? News websites in particular. There have been times that I have searched for an article I saw on the front page barely an hour ago and the website won't turn it up, even if I type in the actual headline. You usually get some old, un-relevant shit like "Girl Scout Sock Hop Raises Money For Rabbit Herpes" after typing in "Drone Attack In Yemen". Honestly the best way to find anything is through Google. Actually the really best way is through Google Images, type in just a few words and scan through the pictures, you're almost bound to find whatever you want, no matter how obscure.
There are a few exceptions to this, You Tube, Wikipedia and maybe some forums. Other than that there's no point in bothering. Moral: if you see a link you like bookmark it before it disappears into the abyss..
