Use multiple databases/search engines. There will be overlap in what you find, but each will have something unique.
Extrapolation is key. Keep in mind that you will need to pull pieces of information from various articles to make your point. You may not – probably won’t – find the perfect article that sums up your position.
Take notes as you go. It’s really hard to find or document things after the fact. So track where you search, the terms you use, and the citations you find as you go. Paper or online doesn’t matter. Just track it. If an article looks *remotely* useful, make note of it. Better yet, put it in Mendeley or Zotero (see Citing Sources tab). It’s always easier to cross it off later than try to find it again. (Sometimes you can’t find it again. I’ve learned that the hard way.)
