How to search for jobs without a specific job title?

I hope this makes sense. In my search for a job, I'm looking for anything I can get my hand of but I'm not sure what keywords I can put in to find something. I have a bachelor's degree in criminal justice. I've been been putting in criminal justice to try and find something closely related but there's really nothing new to find each day. Any type of office work would interest me even outside of that field but I don't know what words to search. I use to do something like background screenings for employment reasons and wouldn't mind finding work similar to that but i again don't know what to put in the search bar to find something. Any advice?
