Result:
EXCEPTION: expected string or buffer

You didn't supply a call example, but I can see one potential problem. If 'field' is like tags then the result from mi.get will be an array (in python a 'list'), not a string. If you know that 'field' is always 'like tags' then you can solve this problem using

	import re
	f = ','.join(mi.get(field))
	if re.search(val, f):

If you don't know then you can do something like

	import re
	f = mi.get(field)
	if isinstance(f, list):
		f = ','.join(f)
	if re.search(val, f):

We are getting very technical here.
