Abstract
A system, computer readable medium and method for searching for recently altered documents on the World Wide Web is provided. The method selects a server to be searched or crawled by a Web crawler based on a user selected ranking. Servers are ranked by a filter program which compares a user query with the content of a server and the frequency in which content is altered. A top percentage of ranked servers are crawled and the recently altered information, such as hyperlinks, are then provided to the user.
