is in() function only used with if() and case() or also with validate() ?

[CyberAar]

I am asking this question because I was studying one of the tutorials and the quiz question says it is NOT applicable to validate(). Based on what I understood, in() function can be used in validate(), case() and if().

I verified it by running a search. Not sure why validate() is an incorrect option. Thoughts?

I don't know where you got this limitation. It's a normal function returning boolean value and as such must be used in boolean-accepting context like eval, case or validate functions or where command.

@CyberAarI would recommend not posting Splunk quiz questions in the Community. It would be more beneficial to go through the course videos and documentation thoroughly before attempting the quiz.

The in function must be used with functions like case and if to evaluate conditions and return results based on those conditions.

• case: The case function allows you to evaluate multiple conditions and return a value when a condition is true. It can be used with in to check if a value matches any of the specified values in a set.
• if: The if function evaluates a condition and returns one value if the condition is true and another if it is false. It can be used with in to create conditional logic based on whether a value is in a set.

The validate function is not a standard SPL function. It is not designed to work with the in function or to evaluate conditions in this context. Instead, validate might be confused with a custom function or a term from another context, but it does not apply here in Splunk's SPL.

May I know what does "not a standard function" imply? In the official tutorial, validate() function has been also explained along with if() and case(). Works similar to case() but does just the opposite of it. 

Thanks for mentioning about posting the content. I have removed it.
