Where do you find all these great synonyms? There are a couple of good strategies you can try once you're done brainstorming:

Talk to someone else who knows what you're looking for, maybe a classmate. They may have heard it called something else.
Explain your topic to someone who doesn't know what you're looking for. This can broaden your search.
Try searching a library database with your keywords and see what articles say. What language do they use?
Try the inverse. Make sure you're including keywords for both sides of a two-sided issue.

With these in mind, let's add some more synonyms to our table:
