Where do I find help turning my topic into a question?
The databases in the box above, for example, Opposing Viewpoints in Context and CQ Researcher, may provide examples of questions or statements in the articles - you may need to look inside the article, not just at the title.

Once you have formulated your research question, you need to identify key concepts and their related keywords.
1. Eliminate the words in your research topic that will not help you retrieve relevant articles. What you have left will be the keywords you'll search:
How can robots help nurses do their jobs more efficiently?
2. If you ended up with more than 3-4 keywords, think of the most important ones. It's best to add keywords later if the results are too broad.
3. Think about whether there are synonyms or related terms that you might want to search in addition to your main concepts. (You want to try to predict what other terms authors might have used for your topic.)
An asterisk (*) will find multiple forms of the word. For example, robot* will find robot, robots, robotic, robot-assisted, etc.
