A system and related techniques generate alternative search terms derived from a set of search results. A user may input a set of search terms such as keywords or other inputs, and receive a set of search results back, for instance in rank order of estimated relevance to the user's search terms and search intention. In addition to the hyperlink or other results may have associated with them a set of selectable alternative search links, for instance indicating "show me more with titles like this" when for instance a Web page title contains the user's search terms. Other results may present other attributes, depending on the evaluated distinctiveness potential alternative information content of attributes of that Web page or other result, which attributes may further include, for example, the presence of image files, PDF(TM) files, audio or video files or attachments, Web pages or other hits indicating certain date ranges, or other attributes or characteristics. In embodiments an attribute or attribute of a result may be assessed for inclusion as an alternative search attributes or limiter based on the attribute's deviation in an attribute space from an average of the attributes of the original set of search results, or otherwise. A user may click or otherwise select the alternative search suggestion, for instance indicating "show me more PDFs" and be presented with an updated set of search results containing Web pages or other hits, links or results each of which is, contains or has attached a file or content of that type. Users may thus receive categories of search results more closely aligned with their search intent when characteristic attributes may be a factor in desired content.
