When beginning research on a new topic, there are a few general items that are useful to keep in mind:
Database searching, more than anything else, is a trial-and-error process through which you search the databases. Searching requires trying various keyword combinations to determine the best combination for finding on-topic research. You often will need to try several keyword combinations before you start to find articles that are related to your topic.
It's not unusual to pick a topic and then discover a "literature gap" - meaning that there are very few, or maybe even no published articles on your specific subject. It's okay to change topics if there isn't enough research to work with.
