Answer
Boolean Operators are tools used in creating searches in EagleSearch, as well as a variety of other research databases. The search tools you use may vary slightly depending on the specific database. The most common Boolean Operators used in EagleSearch are as follows:
- AND is used by most databases to ensure that each term is present somewhere in the search results: NextGen AND flight
- Asterisk (*) acts as a truncation character to allow for variant word endings: refuel* = refuel, refueling, refueled, etc.
- Quotes instruct EagleSearch to search for the enclosed terms as an exact phrase: “human factors”
- OR is used between terms to indicate that any term is acceptable: (aircraft OR airplane)
- () Parentheses order and combine search concepts: “human factors” AND (aircraft OR airplane)
