A search result set is communicated to a first user as hypertext descriptions of data items constituting the result search set. A check box is displayed adjacent each hypertext description, utilizing which the first user may select a subset of the search result set. This subset is then communicated to a second user, again as hypertext descriptions of the subset. Check boxes are furthermore displayed to the second user so as to enable the second user to select a further and narrower subset of the search result set. Selected items of a result set of an Internet-based search may in this way conveniently be communicated between first and second users. Each of a number of interfaces provides the hypertext descriptions of the data items of the search result set.
