The operator used for pattern matching with wildcards in Splunk is the "like()" operator. This function allows for the use of wildcard characters, particularly the percent sign (%) to represent zero or more characters and the underscore (_) to represent a single character within a string. This capability enables users to perform flexible and dynamic searches when they are unsure of the exact contents they are looking for. For instance, searching for a pattern like "error%" would match any string that starts with "error" followed by any combination of characters.

The other options do not have the same functionality as "like()". The equality operator (==) is used for exact matches and does not allow for wildcards. The function includes() is typically used to check membership in a collection or set, while contains() is used for checking if a specific substring exists within a longer string, but both lack the wildcard capabilities that "like()" provides.
