It is important to identify the main concepts of your research question. Why, you ask? Great question. (Pardon the not so lengthy answer)...
Databases, while smart, do not have the fancy computing power (also known as algorithms) that Google has. Google can understand the context of a question because they have boatloads of $$ to pay programmers to identify search trends and develop algorithms. Database companies, do not have boatloads of $$. So, they have designed databases to search for EVERY WORD that is typed into the search box, without considering context.
You, the researcher, need to identify the MOST IMPORTANT words in your research question so that YOU can control the context of your search.
My favorite example:
If you search "How high do cats jump" in Google, you get articles on LITERALLY how high a cat can jump.
If you perform this same search in an academic database, you will get articles about cats (domestic and wild), jumping (anything that jumps), and height. OH, AND ALSO illicit drug use because "high" is a term that is used to describe the mental state of someone (or cat - they do love the nip) who is using drugs.
This video shows how to identify keywords/ key terms. Consider it a new super power. YOU'RE WELCOME.
