Wildcard Searches

Howdy everyone,
I was wondering if anyone knows of a wildcard character for when searching via Metro search? If I just input a partial word, it will bring up results with that text in it, but what if I want to use a wildcard phrase within it.

For example - I want this type of search:

"Bo* Builder Corporation" - It will not generate any results, even though I know there's a document titled "Bob Builder Corporation"

Thanks for any help!
