The following search techniques are often used in database searching:
- AND is used in most databases to ensure that each term is present somewhere in the search results: aircraft AND accident AND recip*
- The asterisk (*) is a symbol which allows for variant word endings: malfunction* = malfunction, malfunctioning, etc.
- Quotation marks are used indicate that the words enclosed must be searched as a phrase: "reciprocating engine*"
- OR is used between terms to indicate that either term is acceptable: aircraft OR airplane
Suggested search terms (examples of terms that might be used in your searches):
reciprocating, engine*, malfunction*, failure*, accident*, investigat*, power plant, powerplant
Search examples (sample searches using various terms and combinations of terms):
- reciprocating AND engine AND failure*
- recip* AND engine AND accident*
