The shlex approach, finished:
searchstring = 'moo cow "farmer john" -zug'
lexer = shlex.shlex(searchstring)
lexer.wordchars += '-'
poslist, neglist = [], []
while 1:
token = lexer.get_token()
# token is '' on eof
if not token: break
# remove quotes
if token[0] in '"\'':
token = token[1:-1]
# select in which list to put it
if token[0] == '-':
neglist.append(token[1:])
else:
poslist.append(token)
