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: words that contain occurrences of one or both of the wildcard characters * and ?, and literal words that do not contain wildcards.

•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A literal word in a query expression matches the same word, character for character (case ignored), in an archived document.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.
