Hit "remove" by accident on webpage results. How to undo it?

This is BEYOND frustrating! By accident, I hit the "X" box on a google search, the one that removes the result from your search list. I have looked everywhere and can't figure out how to remove/reverse that mistake. I've tried the "promote" option, I've tried editing my account preferences. NOTHING works. And to make matters worse, Google has a system set up where you can't just email them directly, it's all a FAQ type loop. Yet, I can't seem to find it IN the FAQ. Does anyone know how to fix this? I hate having to type out the entire website address and search through to find it now that it doesn't come up at the top of the results because I removed it by mistake. It's just really annoying when you're trying to find something quickly. Any help would be appreciated. Thanks.
