Well, not exactly. It finds the longest "rightmost" match it can.
Searching backward, once it has found a character that can serve as
the beginning of a complete match, it then still finds the longest
match possible starting from that point. For example, starting with
(point) just in front of the "b" in "fooooo gooo bar",
(re-search-backward "[fg]o*" nil t) will find and return "gooo", not
just "go", as the string returned by (match-string 0).

It sounds to me like the functions skip-chars-forward,
skip-chars-backward, skip-syntax-forward and skip-syntax-backward
will probably serve you well.
