Alta Vista provides simple and advanced searches on the largest Web index: 31 million pages found on 1,158,000 servers, and 4 million articles from 14,000 Usenet news groups. Because of the extensiveness of its database, Alta Vista excels at finding obsure bits of information virtually anywhere on the web.
Excite tracks down information by searching for concepts, not just by keywords using a search technology called Intelligent Concept Extraction. It claims to search the full text of 50 million web pages, 60,000 categorized Web site reviews, and thousands of recent Usenet postings. Excite is among the best of the search engines at staying current.
Unlike other current generation search engines, which rely heavily on keywords or meta-search technology to find information, Google offers an advanced patent-pending technology called PageRankTM to deliver the most relevant results. PageRank ensures that the most important, relevant pages always come up first and that your users will always find what they are looking for. The PageRank algorithm was developed at Stanford University by leading computer scientists for more than three years before the company was formed.
A joint venture between Inktomi and Hotwired, HotBot is a full-text search engine powered by the Inktomi parallel-processing search engine. HotBot claims to index over 54 million Web pages and promises to index 100% of the Web and Usenet news and mailing lists. HotBot offers the ability to search by date, resource (Java, Shockwave, VRML, etc.) and location.
