Why YSK: Searching topcs on reddit was simple matter of entering desired term and prepending or appending keyword reddit. With lemmy’s decentralised structure finding particular topic without knowing to which, or rather if even there is community dealing with such topic(s) can be a headache inducing hurdle. So appending simple:
site: lemmy.*
site:lemmy.*
to Your google search feature can ease up search.
P.S.
to avoid certain domains You can use e.g.:
-site: beehaw
-site:beehaw
@edit: removed spaces thank You @inquisitor1965@kbin.social
Somebody posted a tool that handles this sort of searching for a number of popular instances that do not fit the usual patterns, see https://kbin.social/m/fediverse/t/52753
