EC 596/597 Graduate Student Research Resources: Searching Databases

This guide assists students enrolled in EC 596/597

Basic Search Mechanisms (Boolean)

Be sure to use Caps for AND, OR, NOT when searching.

AND - searches for papers and articles containing both terms. Example: China AND Trade

OR - searches for one of the words. Example: British OR English

NOT - exclude a term. Example:  Wales NOT England

Parenthetical notes () - excellent for OR or NOT searches. Like a math equation, the database will do this part first.
Example: (British OR English) AND trade = search for British or English trade.
Example: (Oregon NOT Portland) AND Crime = search for crime in Oregon, excluding Portland.

Quotation Marks ""- Links words together in the search. Works best for phrases or proper names.
Example: "United States"
Example: "Portland State University"
Warning: You might exclude results. A search for "Republic of Ireland" will exclude all results for "Ireland." 

Asterisk * - Allows you to search several word endings at once, without using OR.
Example: America* will give you results for America, American, Americans.
Example: econ* will give you results for economics, economic, economists, economical, econometric...
Example: Brit* will give you British, Britain, Brits.
Warning: You may get unexpected results. Brit* will also yield Brittany, Britons, and Britches.

"Trans Pacific Partnership"

4) Based on the key words, use boolean to create a search using AND and OR (See Search Techniques tab)
