The details discussion of how search and route-only domains work is in systemd-resolved.service(8). But users are more likely to look at resolved.conf(5), because that's where Domains= is described. So let's add a reference to the other man page there, and also strengthen the text a bit. In particular, in systemd-resolved.service(8) we say "route-only", which makes the distinction with search domains clearer. Let's use the same in the other man page too. This is based on feedback from Lukáš Nykrýn that the man page is not clear enough.
