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.
Use truncation (*) to retrieve multiple versions of a word; for example:
will retrieve child, children or child's
Here are other examples using OR and truncation:
(teen* OR adolescent*) AND (heroin OR marijuana OR drug abuse)
(child* OR teen*) AND (ADHD or attention deficit hyperactivity disorder) AND (medication or Ritalin or Methylphenidate)
Be sure to use parentheses to keep the words you combine with"OR" together.
When you are trying to find arguments on a particular side, the words "pro" and "con" may not work and words like "for" and "against" may be ignored by the search engine.
Here are some terms to try:
|Both sides of the debate||"Pro" arguments||"Con" arguments|
