The '*' symbol in a patterns means 0 or more of the previous character, so it finds a slash, a space, then 0 more spaces. If you want to only find strings that have at least two spaces, use '+', which means one or more.
l:find('\ +')

Oh i see, never knew * had an role in patterns.
What I wanted it to do is look for '/ *' in a string, how can you do that then?

It'd be "/ ." if you want the * to stand for any character, or "/ %*" if you wanted a literal *.
