One thing you can do is search over the range from "username:" to "username;". "username:" is the first possible string starting with "username:". "username;" is the first possible sting after all of the stings that start with "username:" . This works because ; is the character right after : in ASCII. I believe that UNICODE is ordered similarly to ASCII, though I am not 100% sure on that issue.

I will have to use composite Super columns name, i.e. "username:userid", i know that is a lot of different ways to deal with this case, but once i have modeled with composite Super Columns name is there any way to make a sarch over only one part of the column name? And if so, it works for normal columns too? Sorry about the English, I know it is not so good, and thanks for answers.
