To make it searchable on your password, someone would have to go through the Adobe set and use the hints to manually figure out the clear text form. Off hand, it's hard to see how posting that on the web could be done responsibly.
But until someone does, you could just Google "most common passwords" and if yours is in the set, you win!
no, you have known plain text, so you just have to encrypt your password using the same algorithm and then search the database for matching ciphertext, there's no need to find the clear text for any of the passwords.
you can't re-encrypt since we don't have the keys. but you can search for your e-mail, pull up the associated hash, and then search for the hash to see who else used that password, and list all of their password hints.
