RKWard does, too. (More precisely: It has a UI for searching help files, which 
relies on help.search()).

Will this affect the structure of the hsearch class?

Currently, our implementation for showing an item from the result list is to 
simply call help(help_type="html"), appropriately. What are the implications 
of vignettes for the behavior of help(), if any (with or without specification 
of help_type)?
