1 a.  MEANING OF SEARCH ENGINES

A web search engine is a software system that is designed to search for information on the World Wide Web. The search results are generally presented in a line of results often referred to as search engine results pages (SERPs). The information may be a specialist in web pages, images, information and other types of files. Some search engines also mine data available in databases or open directories. Unlike web directories, which are maintained only by human editors, search engines also maintain real-time information by running an algorithm on a web crawler.

1 b.       5 TYPES OF SEARCH ENGINES

1.     Mocavo is a privately held Internet company based in Boulder, Colorado, United States. It is a for-profit, genealogy search engine with millions of records and historical documents online; it provides a number of tools such as family trees and advanced search features for genealogical and historical research.

 

2.     Google Scholar is a freely accessible web search engine that indexes the full text of scholarly literature across an array of publishing formats and disciplines. Released in beta in November 2004, the Google Scholar index includes most peer-reviewed online journals of Europe and America's largest scholarly publishers, plus scholarly books and other non-peer reviewed journals. It is similar in function to the freely available CiteSeerX and getCITED. It is also similar to the subscription-based tools, Elsevier's Scopus and Thomson ISI's Web of Science. Its advertising slogan – "Stand on the shoulders of giants" – is taken from a quote by Isaac Newton and is a nod to the scholars who have contributed to their fields over the centuries, providing the foundation for new intellectual achievements.

 

3.     Bing Health (previously Live Search Health) is a health-related search service as part of Microsoft's Bing search engine. It is a search engine specifically for health-related information through a variety of trusted and credible sources, including Medstory, Mayo Clinic, National Institutes of Health's MedlinePlus, as well as from Wikipedia.

 

4.     Google News is a free news aggregator provided and operated by Google Inc, selecting most up-to-date information from thousands of publications by an automatic aggregation algorithm.

Launched in September 2002, the service was tagged as a beta test for over three years until January 2006.The initial idea was developed by Krishna Bharat.

5.     Ask.com (originally known as Ask Jeeves) is a question answering-focused web search engine founded in 1996 by Garrett Gruener and David Warthen in Berkeley, California. The original software was implemented by Gary Chevsky from his own design. Warthen, Chevsky, Justin Grant, and others built the early AskJeeves.com website around that core engine. In late 2010, facing insurmountable competition from Google, the company outsourced its web search technology and returned to its roots as a question and answer site. Douglas Leeds was elevated from president to CEO in 2010.

 

Ask.com is noted and most infamous for a malware toolbar that can be surreptitiously bundled in with legitimate program installations, and which generally cannot be removed from most common browsers once installed.

 

Three venture capital firms, Highland Capital Partners, Institutional Venture Partners, and The RODA Group were early investors. Ask.com is currently owned by InterActiveCorp under the NASDAQ symbol IACI.
