Boolean logic A search for ‘rock AND roll’ will locate all records containing both the word "rock" and the word "roll.” (same as ‘all’) A search for ‘rock OR roll’ will locate all records containing either the word "rock" or the word "roll" -- not necessarily both. (same as ‘any’) A search for rock NOT roll will locate records containing the word "rock" but NOT the word "roll" .
Truncation To find words that have the same root or ‘trunk’, use truncation. For example, truncate the root adolesc* to retrieve: adolescent adolescents adolescence, etc.
