Using \(Word1\)\|\(Word2\) works for me. If you find it troublesome to
type a lot of these escaped parens, you might want to try
smartparens-mode for auto insertion of the closing _escaped_ paren.
As an example, if you type "\(", smartparens will automatically insert
"\)" after point. You can even navigate over these groups via sexps
commands.
