How can I can not find a user with spaces in their names?

I try to search user:"Nam Gi VU" But I got no results, how can开发者_如何学运维 I search using this name? (The name can be any names, I just get my name as an example.

I'm going to go out on a limb here since you haven't specified a lot about the environment.

If you're running on a UNIXy-type box, you can simply use something like:

egrep -i '^nam +gi +vu$' /path/to/usernames.txt

The + indicates one or more of the preceding character so it will find the words nam, gi and vu with spaces between them (the -i means ignore case).

If you're allowed to have spaces at the start and end, use:

egrep -i '^ *nam +gi +vu *$' /path/to/usernames.txt

(* means zero or more of the preceding character).

If you have a more advanced regex tool, you can use \s for white space and \b for word boundaries.
