h1. Wildcards Wildcard characters are special characters that are interpreted when comparing text. There are three meaningful wildcard characters: ? - matches a single character * - matches everything (including nothing) & - matches a whole word if used alone For example the expression *t*s a *?t* matches the string *this is a text* If & is not used alone it matches the plain text '&' character *test &* matches *test this* or *test that* *test &his* matches only *test &his* *test thi&* matches only *test thi&* *test th&s* matches only *test th&s*
