Hi Victor,
If this is a elementary search help then there would be no event and you can put debugger in get_v method to check the logic.Also you can check in se11 if the search help is giving the desired result.
Now in case you need a search component in the F4 then in get_v method call the outbound plug and write the logic to create pop up and also event for handling once you close the pop up..
Let me know if my understanding is correct and it helps you.
Regards,
Saurav
