First, the names of fields are case-sensitive. You created a field named "test" but then your top command used a field called "Test". That's never going to work.

Second, although your regular expression may be legal, I would have written it:

(?im)(?<test>"(?:Request|Response)") 

I have noticed that Splunk is sometimes finicky about non-capturing parenthesis; this regular expression is a bit clearer. And are the quotation marks actually in the data? Do you really need them for the regular expression?
