Keyword Searching

Use the Search Generator from Northwest Missouri State University to help you create a keyword search. 

                        Using AND/OR/NOT (Boolean Search Operators)


Use AND to focus search and combine different aspects of your topic.

Example: vegetarianism and environment


Use OR to expand your search and find synonyms/related terms.

Example: global warming or climate change


Use NOT to exclude a word or phrase from your search

Example: emissions trading not United States


Additional Search Tips

"Phrase search"  - Use quotation marks (" ") to search for a particular phrase.

Example: "greenhouse gas emissions"

Truncation * - Use an asterisk to find variations of a word. Put an asterisk following the root of the word to find all variations of that word, including singular and plural.

Example: environment* (finds environments, environmental, environmentalist, etc.

(Grouping/Nesting Keywords) - Use parentheses ( ) as a way to group all your search terms together.

Example: (climate change or global warming) and population growth
