looking for keys on a keyserver with gpgme

I have an issue looking for keys on a keyserver. Specifically the
listing returned is always empty. This is my code, written with the
help of Werner Koch, useless parts removed:

        gpgme_keylist_mode_t mode = gpgme_get_keylist_mode(ctx);
        mode &= ~GPGME_KEYLIST_MODE_LOCAL;
        err = gpgme_set_keylist_mode(ctx, mode);

        err = gpgme_op_keylist_start(ctx, id, 0); /* id is a string */

        while (!err) {
            err = gpgme_op_keylist_next(ctx, &key);

            if (err) {

            /* if the KEY has the same ID as the one I'm looking for,
proceed... */

I believe the error is in the second argument of
gpgme_op_keylist_start, where I'm asked to provide a search pattern.
I'm not sure how patterns work, so I first tried an empty one (which
works when I'm listing keys from the local keyring with the same
procedure), and then the ID with or without a leading "0x". In both
cases the listing stop at the first call to keylist_next with "EOF".
The keyserver should be correctly configured: it's in both the global
gpg.conf of my user, and in another gpg.conf in the keyring used
within this application. What am I doing wrong? :)

Thanks everybody,
