The research process is just that: a process. A good researcher isn't someone who can always put the right words in the search box the first time, it's someone who uses each search to improve the next one.

To do effective research, you might need to circle back and try more than one search, use more than one database, and look at more articles than you actually use. By thinking through your research topic in advance, you'll be better equipped to plan how long your research takes and decide which sources will be the most helpful for you.
