Hi all, "resolvectl -i INTERFACE query" fails if global DNS is used. [1]
I might be mistaken, but according to resolvectl man page [2], "resolvectl -i INTERFACE query" should be equivalent to "resolvectl query" in this case, and it should resolve domain names successfully.

This may either be specified as numeric interface index or as network interface string (e.g. "en0"). Note that this option has no effect if system-wide DNS configuration (as configured in /etc/resolv.conf or /etc/systemd/resolved.conf) in place of per-link configuration is used. Thanks, Bing-Hua
