Keywords/synonyms

It is important to realize that if you search a database with a certain word or phrase and you don't retrieve results to your liking, it doesn't mean that there are no other articles in that database on your topic. It may mean that you need to try other related words in your search, such as synonyms. For example, try automobile or auto instead of car.
