Building a search
- Start with just a few broad keywords:
Example: human AND "gene editing"
- If these keywords return a large number of results, you can start adding terms with the boolean AND operator:
Example: human AND "gene editing" AND controvers*
- You can also broaden a search by searching alternate terms, in parentheses, separated by the boolean OR operator.:
Example: human AND "gene editing" AND (controvers* OR ethic* OR moral*)
- There's alot of trial and error in keyword searching, but it can often be a very effective way to search
Example: human AND "gene editing" AND (controvers* OR ethic* OR moral*) AND inequality
To find articles in databases, start by combining one or two key words and phrases
Use an asterisk to find variant endings, e.g. ethic* finds ethics or ethical
In some databases, it's helpful to place "quotation marks" around phrases.
In most databases, you can also limit your search results to scholarly, or peer-reviewed, journals.
Narrow your search by adding terms.
There are several ways to broaden a search:
- Remove some terms
- Include alternative terms in parentheses. Example: (controvers* OR ethic* OR moral*)
- Truncate terms to pull up variant endings, e.g. controvers* finds controversy or controversial
