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"
