I have no idea if that is supposed to work, but I noticed what appears 
to be a problem:

0e35-353ad7-3ad71b-d71b

Can not be parsed with :

([a-z0-9]{2})([a-z0-9]{2})([a-z0-9]{2})([a-z0-9]{2})([a-z0-9]{2})
([a-z0-9]{2})

Because ;
1) 0e35-353ad7-3ad71b-d71b is 24 charcters not 12
2) You have no provisions for '-' characters.

So your search will not get a match.
