It seems to me that \concept{} is simply another code for "My keyword is your search term". I do not consider myself to be one of the better informed users of R, yet the frequency with which I resort to a full text search is less than once a month. For such an infrequent task, I find it no problem to fire off a full text search of the help files and occupy myself otherwise for a minute or two.
