Wildcard characters are special characters that are interpreted when comparing text.
There are three meaningful wildcard characters:
? - matches a single characterFor 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
