Articles & Reviews
When Searching Is No Longer Enough. Internet Retailer; April 2002 by Kurt Peters
Discusses online store search engines: Mercado, EasyAsk, Endeca, and Netrics, referring to the 2001 Forrester report. Describes customer needs for technology that allows both searching and browsing by category or product attribute. Includes evidence of the good results at Tower Records with Endeca, but finds few examples of faceted metadata usage. Includes additional references to studies of e-commerce search engine demands and limits, suggesting significant changes from the traditional "relevance ranking" approach. Changes include recognizing the problems of a long search result, redirecting searches for brands or products not carried to similar available products, sorting and drilling down on product attributes, spelling correction and synonyms
