Unless you've lost me somewhere, you're describing something like this:

s = 'abcd'
a = re.compile (s)
b = a.search ('a')

which means, "find a match of the pattern 'abcd' in the string 'a'....
probably not what you mean.  The "None" simply indicates that there is
no instance of 'abcd' in 'a'.  What you want here, is

s = 'a'
pat = re.compile (s)
b = pat.search ('abcd')
