GOOGLE Recently introduced a search-within-search feature that lets users stay on Google to find pages on popular sites. The search box appears when someone enters the name of certain Web addresses of company names. Users are shown a search box as part of the result within some of the srarch results themselves. According to Google, this feature will show up when there is a high probability that a user wants more refined search results within a specific site. The sites that display the site search box are chosen algorithmically based on metrics that measure how usefuul the search box is the users. Some companies are alarmed by this, since it leads to a loss in ad-revenue. The feature also keeps users searching on Google pages and not pages of the destination Web site.
