This function calls the right function with the right arguments. It directly return the result of that call. Text is a text widget. Prog is a precompiled pattern. The ok parameter is a bit complicated as it has two effects. If there is a selection, the search begin at either end, depending on the direction setting and ok, with ok meaning that the search starts with the selection. Otherwise, search begins at the insert mark. To aid progress, the search functions do not return an empty match at the starting position unless ok is True.
