I've tried to add the dot, and yes, that stops sending the another query.
That's easy to handle when you actually send a ping to an invalid
domain, or something like that. But what about all the other applications
that send many DNS requests and some of the domains simply doesn't exist?

Look at the DNS stats:

dnsmasq[1582]: time 1452266531
dnsmasq[1582]: cache size 10000, 0/2811 cache insertions re-used unexpired cache entries.
dnsmasq[1582]: queries forwarded 3205, queries answered locally 4028
dnsmasq[1582]: queries for authoritative zones 0
dnsmasq[1582]: server 192.168.1.1#53: queries sent 363, retried or failed 0
dnsmasq[1582]: server 208.67.222.222#53: queries sent 2, retried or failed 0
dnsmasq[1582]: server 127.0.2.1#5353: queries sent 2840, retried or failed 18

Most of the 363 queries that were sent to the local network router are
those with "mhouse.lh" appended to the invalid domains, and not
hostname.mhouse.lh . I'm just trying to eliminate the queries. Is there
anything I can do about it, except removing the "search" line from the
/etc/resolv.conf file?
