#
The mandated wild card character stands for one character within a word or at the end of a word. For example, organi#ation finds occurrences of organization and organisation, and dog# finds occurrences of dogs but not dog. It can be useful for irregular plurals. For example, wom#n finds occurrences of woman and women.

?
The optional wild card character stands for zero or one characters within a word or at the end of a word. It is useful for retrieving records with British and American spelling variations because it finds words whether or not the extra character is present. For example, a search for colo?r finds occurrences of color and colour.
<rootword>$<n> or Limited right-hand truncation restricts the number of characters following the word. For <rootword>*<n> example, a search for dog*1 finds occurrences of dog and dogs but not dogma.
