Matching words
Matching words is not case-sensitive: cat, Cat, cAt, and CAT all match. Corresponding uppercase
and lowercase letters, such as A and a, are treated the same in all respects.
There are two kinds of query words:
• Literal words that do not contain wildcards
• Words containing occurrences of one or both wildcard characters * and ?
A literal word in a query expression matches the same word, character for character (case ignored),
in an archived document. A word with wildcard characters (* or ?) matches a document word in the
same way, character by character, except for the following:
• A ? matches any single character in a document word. For example, b??t matches beat, beet,
boat, blot, best, bust, bout, and so on.
• An * matches any sequence of characters in a document word, including a sequence of no
characters. For example, f*t matches the document words foot, feet, fit, fault, and ft; and f*
matches any document word beginning with f.
You can use any number of wildcard characters (* or ?) in a query word, but you cannot use a
wildcard at the beginning of a query word. An error message results. For example, *ion is not a
valid query.

Fuzzy words
You can search for document words that are textually similar to a given literal query word (that is,
one containing no wildcards). To do this, append a tilde (~) character to the word, creating a fuzzy
