what is the "search domain"

This means that if you try to resolve foo in bar.tld to an IP it will succeed given your search domain is bar.tld. If search domain was not configured you would have to use foo.bar.tld to correctly resolve foo to an IP.
hello and thanks for your reply. unfortunetly i don´t understand quite well. Does this mean if e.g. a container is running under foo.bar.tld it will not be found if the search domain isn´t bar.tld? I am a little confused and not an expert as you see on my 3 (now 4) postings 
The practical use for this is if you want to use local DNS in your network to refer to systems by name easily (particularly if in a Windows controlled network with DC).
For example:
-On your DNS server you can create a zone such as mybusiness.com.local then have some dns records for your non-routeable IP resources like:
-Create a record called myemailserver.mybusiness.com.local pointing to 10.0.0.100 (example ip address)
-Your server/vm/PVE will now be able to resolve "myemailserver" to 10.0.0.100.

What is the normal default search domain? I'm having frequent connectivity issues with the server from other subnets.
Mine is set to 'lan' right now but I'm not sure if that was a modification of the default or not - Not sure how to revert or reset without reinstalling.

I believe it is unset, but don't quote me on that.
I run DD-WRT on my router and have a custom LAN DNS using '.home'. For my 3 physical nodes, I set their default search domain's to that.
It is very simple, .... when you try to resolve any host, if the system can not solve that host, he try again using host.${search domain}. And if your host that you want to resolve is not FQDN(like gigi007), then the resolver will try from the beginning to find gigi07.${search domain}
