Explanation:
A wild card is one form of advanced search technique. It is mostly used to maximize the user's search results in library databases. This is used mainly to search for terms for signifying one or more other characters.
The frequently used wildcards are an asterisk (*) and question mark (?). The asterisk symbol is used to symbolize any number of characters. Thus, (*) operator is used as a wild card character in Base.
