You are not expected to be an expert in your chosen research topic area. A quick way to spin up on a topic(s) you are interested in researching is to read a general encyclopedia article.
Reading a broad summary enables you to get an overview of the topic and see how your idea relates to broader, narrower, and related issues. It also provides a great source for finding words commonly used to describe the topic. These keywords may be very useful to your later research.
If you can't find an article on your topic, try using broader terms and ask for help from a librarian.
