Correction to search please

I sell some items from the company called Stampin'-Up!.

When I do a search using Stampin'-Up, I get my results. When I add in the exclamation mark (which is part of their officially trademarked name), I get no results.

Some people who know the company and are specifically looking for their items may not be able to find my items if they use the full company name. Can you please fix the search to the the exclamation mark can be optional and the person still see the items please?

thanks
