WildcardQuery specifies the configurations of a wildcard query. This query retrieves data that matches a string. The string can contain two types of wildcard characters: asterisks (*) and question marks (?). The asterisk (*) matches a string of any length at, before, or after a search term. The question mark (?) matches a single character in a specific position. The string to match can start with an asterisk (*) or a question mark (?). For example, table*e matches tablestore.
