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*
