I’ve found a plunger useful for a sink occasionally, a bit of back and forth plunging can loosen up a hairball or break a layer of fat/soap scum. On the other hand I’ve never needed to use a plunger on a toilet - I don’t know how much of this is exaggeration on the internet but Australian toilets don’t seem to have anywhere near the amount of issues the American designs do.
I think the main problem with searching for fediverse posts is not that they’re not indexed but the lack of a singular tag to append when you want to search for them. To search for reddit posts it was easy because you could put in your keywords and stick ‘reddit’ or ‘site:reddit.com’ onto the end, but now there’s too many domains to keep track of and you can’t rely on appending ‘lemmy’ pointing a search engine towards all Lemmy instances, let alone kbin/mbin instances.
