The asterisk symbol is also known as a wildcard. In computing and database management, a wildcard is a symbol that represents one or more characters in a search query. Specifically, the asterisk () can be used to represent any number of characters or no characters at all. This feature is particularly useful when conducting searches in databases or search engines where you may not know the exact word or phrase you are looking for. For example, searching for "test" could return results for "test," "testing," and "tester." Thus, it allows for more flexible searching and can help users find relevant data quickly and efficiently.
