LL16 - Method for Search Function in Preview

Hello

Is there a method for using new Search Function within OCX Viewer Control. We are not using LL viewer toolbar, rather designed our own long time ago (and want to add the Search function to it now), and methods for all other LL toolbar buttons are listed in Programmers Manual, except for the Search function.
Am I missing something here.
