You don’t need the + to include things on Google.
Yeah I don’t know why I added that. Kinda dumb on my part.
And just for funsies—you can use related: as an operator to find sites that are similar to something.
I think this is what OP was really looking for. I did a Google search for “ukraine related:lemmy -site:reddit.com” and got this, which seems to be the kind of results OP is looking for:
Yeah I’m new to Lemmy and still getting used to the whole instance thing. Apparently you can use “related:” to include results that are similar. In the below example, I did a Google search for “ukraine related:lemmy -site:reddit.com”.
65???
Look at Richie McMoneybags over here living in his Socialist utopia where he doesn’t have to keep working until he keels over dead on the clock.
Add this at the end of your search query to omit results from Reddit:
-site:https://www.reddit.com/
To specifically include results from Lemmy, you can just add a plus sign and replace the site name:
+site:https://lemmy.world/
Thanks. It’s an homage to my banned Reddit account.
