Regex not matching string (OCaml Str module)

I have this preword and regex:

let regex = Str.regexp "\\([A-Za-z0-9]\\.*[A-Za-z0-9]\\)";;
let s = "--O--c-a-l**9+===";;

My regex is matching for a string that begins with a letter or number, has 0 to as many character in between, and ends with a letter or number. So the substring "O--c-a-l**9+" should match.

But when I see if my preword matches my regex, it keeps saying it doesn't match

Str.search_forward regex s 0;;
Exception: Not_found.

And I'm not sure what I'm missing in my regex for it to not match my string.

You escaped the ., so it will only match literal dots. To match any character, remove the \\.
