Suppose I waant to rsync only index.html and index.php files. use --include & --exclude?

I have a two servers. On the second server I wish to updated only the
thousands of index.php and index.html files via rsync from teh first
server.

I don't want to rsync any other files over--only files with "index" in
their name.

How can I do this using rsync with --include and --exclude?

This doesn't work:

rsync -avz "-e ssh" --include=index --exclude=* /usr/w/var/www
root@server.com:/usr/w/var

Thanks!
