You know when you needed an answer to something and wanted the opinion of the masses. You could search “[how to topic] reddit” or filter with “site:reddit.com”.
So what now? Could i still do “best table Lemmy” or “how to do this Lemmy”?
This was my favorite use of reddit where you could get a bunch of answers for different topics.
It’s going to depend on how content gets indexed.
Doing some quick test searches on Google I think using “site:lemmy.*” gives the best results overall if you don’t know which specific community you are trying to search in.
