Try duck duck go, brief subject, possibly include the word forum or Reddit (I know I know) and then try to narrow down your search terms from there. Use quotation marks for keywords, and site: to denote specific websites that you want to limit your search to.

And that’s basically the magic right there. Another key term to use is if you get too many results of a certain type, like if you search the word constitution and keep getting the ship, include the term -ship and that should remove those results.
