I don't mean to keep self promoting but: https://github.com/marsara9/lemmy-search

It's still a work in progress, but it's going to be a search engine specifically built for Lemmy, and maybe eventually the entire fediverse.

Idea is that you'll be able to search just like you normally would in Google but

1. the links it shows you would take you to your preferred instance
2. it will search as many lemmy instances as it can find, so it won't find anything outside of the fediverse.

Thank god you asked this. It's been like pulling teeth trying to get google to show anything on any fediverse instance

fedi-search.com. Perchance.

I think if you want specifically fediverse answers those are the way to go, but I've had a lot of luck with just adding "forum" on the end of stuff. Seems to give an even split between bulletin forums, Reddit/Twitter, and blogs for any given subject matter.

Google has always been pretty terrible at ranking websites that haven't been around for a while. They are absolutely already indexing every post, they just aren't ranking high enough.

Google will fix it, hopefully sooner rather than later.

You can search by site using the "site" operator, for example:

"whatever you want site:lemmy.world"

All the results will be from/via the lemmy.world instance.

I would probably add either "lemmy" or 'kbin" or both. Not ideal but hey...
