What good is the search box?
 

What can one actually find by using the search box on the main photopost page? I get incredibly inconsistent results. I've tried searching for user names, photo titles, image titles. Sometimes I find what I'm looking for, but usually the result is always the same (pictured below).

What's the trick?

the searchbox is the same as any other search. it searches all relevant things like title description etc just like if you entered a keyword on the actual search page.
