Using quotation marks to search for phrases tells the search engine to search for those exact words in that exact order.
Examples :
Always start by brainstorming keywords before doing the keyword search. First, break the topic down into parts, then brainstorm synonyms, broader terms, and narrower terms for each concept.
For example if your research question was : How do costs for hypertension treatment compare to costs for hypertension prevention?
Concepts | Synonyms, Broader Terms, Narrower Terms |
costs | cost, money, financial |
hypertension | hypertension, blood pressure, heart disease |
treatment | treat, treatments, exercise, diet, "drug therapy" |
prevention | prevent, preventive, prevents, wellness |
If your topic includes a development issue, use terms for that issue in general as well as specific approaches you know of. For the issue, you may also want to use terms for various aspects of the issue as well as the broader term.
Truncation allows you to search for multiple forms of a word with one term.
Examples:
Beware of truncating too short - and getting irrelevant things, for example just cost* would include too many words and all would not be related what you are doing for this course such as costal or costume.
