Repeats the previous character zero or more times. For example, if you need to search for gogle, google, gooogle, goooogle, write like this: goo * gle

Most often, the asterisk is used in conjunction with a period or as part of other regular expressions.

The expression matches zero or more random characters. If it is simpler - any combination of symbols or the absence of symbols. A regular expression can be used in Google Analytics, for example, to set up segments of users with a User ID.
