Bug report... If it's a software fault, they may fix it. If it's not,
they may point out where a configuration problem is.

Do you have to use DHCP? Can you manually configure the network
parameters? You should be able to partially manually configure a
connection and let DHCP automatically do the rest. But you could fully
manually set things.
I wonder if you're running afoul of the systemd-resolved service?
Is the DHCP server under your control? You can specify what it sends
as the domain search parameters (which should end in a dot, as Jeffrey
has already said).
If you always get assigned the same IP, you could put entries in the
hosts file for its addresses, and that'd stop it searching further for
answers.
DNS shenanigans is why I run my own DNS server. Firstly, I started
doing so because my ISP's server was utter crap (overloaded and slow,
and often didn't return results, even for its own services). Then
because I started running a LAN where I needed local name resolution,
the LAN became too big and unwieldy for messing with the hosts file,
and you can only do that on computers.
