No matter if you are in GALILEO or in Google, what you put into the search box matters. Keywords can make or break your search.
Coming up with keywords:
Think of as many different ways to say the same thing.
For example: generic and brand names, acronyms, phrases, jargon, slang, etc.
The more you read, the more keywords you will get. Mining Wikipedia for search terms (and references) is acceptable.
If you are looking for peer-reviewed articles, try to think of the jargon that will be included. This can be hard.
Jargon changes over time and across different fields. Be mindful of this if history is important to your search.
If you find a "perfect article," look to see if there are subject terms or tagged keywords to expand your search.
