To use the ? wildcard, enter your search terms and replace each unknown character with a ?. EBSCOhost finds all citations of that word with the ? replaced by a letter.

To use the # wildcard, enter your search terms, adding the # in places where an alternate spelling may contain an extra character. EBSCOhost finds all citations of the word that appear with or without the extra character.


Truncation is represented by an asterisk (*). To use truncation, enter the root of a search term and replace the ending with an *. EBSCOhost finds all forms of that word.
