Wildcards are represented by a question mark ? or a pound sign #.
To use the ? wildcard, enter your search terms and replace each unknown character with a ?. The database finds all citations of that word with the ? replaced by a letter.
For example, type ne?t to find all citations containing neat, nest or next. Most databases do not find net because the wildcard replaces a single character.
Tip: When searching for a title that ends in a question mark, the symbol should be removed from the search in order to ensure results will be returned.
To use the # wildcard, enter your search terms, adding the # in places where an alternate spelling may contain an extra character. The database finds all citations of the word that appear with or without the extra character.
For example, type colo#r to find all citations containing color or colour.
