• First, no single search engine or portal can locate and catalog the ever-increasing amount of information on the Web in a timely way. Moreover, a huge amount of information is transient and not subject to capture by techniques such as Web crawling. For example, according to research 1 , the world produces two exabytes or about 2x10 18 bytes of information every year, but only publishes about 300 terabytes or about 3x10 12 bytes. In other words, for every megabyte of information produced, only one byte gets published. Moreover, Google claims that it searches about only 1.3x10 8 web pages. Thus, finding useful information in real time is increasingly difficult.
