finding communities

So I joined this morning. Seeing how reddit is declining and starting july 1, my RIF probably stopping I need another place to get my factorio, 3d printing and other subjects fix.

But... I find finding community quite hard here, Are there any tips or tricks. I though using keywords like "factorio", "ender", "klipper" "entitledPeople" (dont judge) would at least give some hits.
