Truncation: The symbol used is usually *. Useful technique, but only works in library databases.
engineer* will retrieve: engineer, engineering, engineers, etc.
Check Subject terms to see if there are any synonym terms to consider in your search. This only applies to library databases, as Google Scholar is only keyword searching, but keep an eye out for various terms you read in articles.
