The function used to check if a value is in a specified list is "in()". This function allows you to evaluate whether a particular element exists within a defined list or set of values. It returns a Boolean output—true if the value is found in the list and false if it is not, which is particularly useful for filtering data and managing conditions within search queries.

For instance, if you are searching for certain IP addresses within a defined range, using the "in()" function simplifies the syntax and makes it easy to verify membership within that list. This capability is valuable for streamlining complex conditional checks, enhancing the overall effectiveness and readability of searches in Splunk.

The other functions do not serve this specific purpose. For example, "like()" is typically used for pattern matching with strings, while "match()" is for regular expression-based matching. "eval()" is a broader function that performs calculations or creates new fields rather than checking for membership in a list.
