What lib to use to find the index of a substring in a string in OCaml?

Question

It seems that String in OCaml has only index of a char, not a substring.

Question:

How can I easily get the index of a substring in OCaml?

What's the best library to do string searching/manipulation in OCaml?

But Str has:

let _ =
    let s = "foo bar string" in
    let reg = Str.regexp_string "bar" in
    print_int (Str.search_forward reg s 0)

The result is 4;
