An item discovery module (IDM) is described that allows a user to find one or more desired items within a store of candidate items. In operation, the user enters a search selection, upon which the IDM determines a collection of matching items. The IDM groups the matching items into one or more buckets, each bucket including one or more items. The IDM then selects representative items for the respective buckets and presents the representative items to the user. The representative items assist the user in converging on the one or more desired items. Namely, the user may enter another search selection which targets an identified bucket, upon which the above-described procedure is repeated.
