Info: "/compare_canditates" error, due to fault regular expression
Detail: Miss a couple brackets, so will match /\d+$/.
Error Flow:
- like "xxx123" will be matched
- index = "xxx123".index('--') || "xxx123".rindex('-')
- index equal "nil"
- r = r[0, nil] will raise an error "TypeError (no implicit conversion from nil to integer)"
Solution: Fill a couple brackets, so will match "vm-abc-0abc-abc" or "vm-abc-0abc-012".

some comments should be provided to better understand regular expressions. Thanks, Liushaofei
Yes, I provided comments on the funtion header.
Thanks, Zhang Yuhang
