How can I search for multiple words (not a phrase, but different words) all at once?

Hello everyone, I have a job that includes looking for many different words in large paragraphs. I would make things much faster for me if - instead of typing in "word 1", and then clearing it, and then typing in "word 2" - but rather, I could somehow search for a few words at once. Is there a way to do this? An add-on? Something built in? Thanks for the help.
