Place quotation marks around two or more words that should be searched as an exact phrase. For example, "human factors".
EAGLEsearch allows for Boolean search operators such as AND and OR; however, the operators must be written in ALL CAPS.
Put "AND" between your search terms to ensure that each term is present somewhere in your search results. For example, pilot AND fatigue.
Put "OR" between your search terms to ensure that your search results contain either search term. For example, aircraft OR airplane.
Parentheses "()" can be used to order and combine search concepts. For example, "human factors" AND (aircraft OR airplane).
Place a * (asterisk) at the end of a root word to search for variant word endings. For example, comput* will find compute, computer, computers, computes, computing, etc.
