Sometimes also referred to as the “deep Web” or “dark matter…what may be invisible today may suddenly become visible tomorrow.” – “If a Web page has no links pointing to it from any other page on the Web, a search engine crawler can’t find it. These “disconnected” pages are the most basic part of the Invisible Web.” Sherman, Chris and Gary Price, In Library Trends 52 (2) 2003: Organizing the Internet: 282-298 – “In fact, only a small percentage of the Web’s content is accessible to Google. The term “deep Web” refers to the vast portion of the Web that is beyond the reach of the typical “surface Web” crawlers. Surface Web search engines like Google can’t easily fathom the deep Web because most deep Web content has no links to it.” Sol Lederman, altsearchengine.com, 2009. 4 So let’s find a typical assignment for a young student 5 My part of the report: “find out what bottlenose dolphins eat” 6 “Regular” Google Search 7 8 9 10 11 Worse results than first Google search! 12 Eliminate the “S” 13 14 AND, OR, NOT + - Google Advanced = Boolean Search + more “ ” 15 16 AND “______” AND AND -______ NOT AND, OR, NOT + “ ” 17 NOT Wikipedia 18 Note: you can actually write this in a Google box and get the same results 19 What was the original question? • What do bottlenose dolphins eat?
