Maybe I did not add the full details, the saved search was created as a reference in the UI, so I am pretty sure it is working fine, I am creating via script the same saved search, the CURRENT_DATE was added just by reference, the user will select a date on the suielet and I will display the information based on that date, so I need to add dynamically the value selected on the saved search created via code.

Sorry. I did misunderstand. I thought you were trying to set a value in a formula(text) field in a saved search
