Search Engines are specialized programs that facilitate the retrieval of data from the Internet, on a business related network or on a personal computer system. They allow users to ask for contents meeting certain criteria usually involving a certain word or phrase, then gives a list of articles that matches those words or phrases. There are number of different engines that can be used for different types of searches and can be narrowed for optimal results.
Before the 1990¡¦s Search Engines were non existent. The first tool to be used for searching the Internet was Archie, which was created in 1990 by a student named Alan Emtage who attended McGill University in Motreal. Searches were achieved by downloading director listing of files on public FTP (File Transfer Protocol) sites. This created a database of files for searching but could not search by file contents.
The first Web search engine was Wandex that was created by Matthew Gray at MIT in 1993, this no longer in exists. Another earlier search engine Aliweb created in 1933 still exists today. The first full text and widely know search engine was WebCrawler which was introduced 1994. Unlike previous search engines WebCrawler became the standard for all future search engines. It gave its users the option to search for any word on any webpage. Since then numerous search engines have became accessible on the Internet. The most popular with total market share and number of searches for April 2007 were:

...Google or anyone else unable to associate that data with the original user. Due to UE stringent privacy laws, search engines like Google, Yahoo, and MSN must find ways to satisfy these laws or face fines.
All search engines are different in some way. The best way to get optimal result is to choose the one that has the features that fits your search. The engine with the most pages in its database is not necessarily the best. You must conduct your search properly such as knowing key search words, avoid mistakes with spelling and use tools that are available such as specifiers for titles, images, links, etc. As search engines continue to evolve they will develop different ways of classifying information in different categories, and provide the search tools to take advantages of these changes. In order to optimize the use of these engines we must evolve with them also.
Search engine industry is built on finding out and also aggresive advertising. As we know there are five major competitors in this industry competing with Google. The competition is strong because they are targeting the same market, presenting similar business and technologies. The five major competitors are Yahoo!, MSN, Baidu, Bing, and AOL.
In 1998, when Google created its search engine, very little data was available about search engines. One of the first search engines was the Wold Wide Web Worm, which was not released unitl 1994. In order to research and create a more dynamic search engine Google’s creators had very little information to go on, and encountered many challenges. It is a challenge to create a high quality search engine as search engines need to crawl and then index millions of pages of information on the web. An additional feature of Google’s large scale search engine is that it will use hypertext information to refine search results. The challenge is to be able to scale the vast amount of data available on the web. The main goal is to improve the quality of search results. The second goal is to be able to make all the data on the web available for academic research. One of the key features of Google that sets it apart from other web search engines is that it is built to scale well to large data sets. It plans to leverage the increase in technological advances and decrease in hardware and storage costs to create its robust system.
Two graduate students, Larry Page and Sergey Brin came together to work on a research project at Stanford University's computer science department. At the time they began working together in 1995, they looked into developing a new search technology that would operate more efficiently and on a completely different principle than existing web search engines. At the time, the most common method utilized by the major search engines on the internet was returns based on how often keywords appear in a particular website. The theory behind Google...
Google founder Larry Page and Sergey Brin created a search engine name "Blackrub" in 1995 whereby it was introduce to Andy Bechtolsheim co-founder of Sun to invest in the company due to the low bandwidth Blackrub have. Moreover, Andy Bechtolsheim invested $100,000 to Larry and Sergey where Andy amazes by the fast speed and relevant the search engine capable in. Therefore, it was then registered under the name "Google" (Ken Auletta, 2009). Google has been well known of their innovative and creativeness in the online engine search providing fast respond and accurate data.
Basic Search TechniquesSince the Google web interface is so easy to use, I won't describe the basic functionality of the http://www.google.com/ web page. Instead, I'll focus on the various operators available:
One of the wonderful things about the internet is how it makes life much easier if the information can be found in the convenience of the home instead of going to a library and making a day out of it. This is especially true if the internet offers updated information as soon as it happens were as a library may only update a few things every week or month at a time. It is truly remarkable how much information can be found and because of this it isn’t unbelievable that more and more people are using the internet instead of going to a library or using another service the internet can offer them. However, without organization and direction information is useless. Search engines offer this stepping stone by storing all the data in a manor that is searchable. Two of the major search engines are Google.com and Msn.com. Both offer great search engines and services, but have different styles and appeal to different audiences looking for different things.
According to Lynch (2008), creating a web based search engine from scratch was an ambitious objective for the software requirement and the index website. The process of developing the system was costly but Doug Cutting and Mike Cafarella believed it was worth the cost. The success of this project unlocked the ultimately democratized algorithm of search engine system. After the success of this project, Nutch was started in 2002 as a working crawler and gave rise to the emergence of various search engines.
There were many search engines prior to Google. But unlike Google, most of them used simple

Google is considered as the leading search engine around the globe. The Google Inc was founded in the year 1998 by the graduate students of Stanford University which are Larry page and Sergei Brin. While studying in Stanford Larry and Brin designed a search engine named as Black rub and after two year they changed the name to Google Inc.
Search Engine Optimization, which is also known as SEO, is the process of increasing the volume and quality of traffic to a website from search engines via organic or search results. The higher your company's website ranks on Search Engine Result Page (SERP), the more searchers will visit your site.
This is an evolving algorithm where both the search engines and the website itself want to capture the needs of the consumer. Through the captured keywords and properly positioned within the website will allow the user to work with the information contained on the website.
When searching on the Internet, one may find it difficult sometimes to know where to start. With the seemingly limitless amount of information, one should use the resource suitable for the searcher's needs and tastes. Comparing different factors like databases, directory types, strengths and weaknesses of two search engines, such as Yahoo! and Lycos, can provide an advantage to someone looking for a starting block.
Search engines, specifically Google, have probably contributed more to the distribution of knowledge than any other invention since the creation of the printing press. Google was created by Larry Page and Serge...
Search engines have many capabilities from using key words or phrases to find what you are looking for to using general statements to browse the web. But what exactly is a search engine? Search engines are huge databases of web page files that have been assembled automatically by machine. There are two types of search engines. One type is the individual search engine. This type of search engine compiles its information on to its own database making it accessible when you use that particular engine. It does not use any other engine?s information to help with your search. Then there are the meta-searchers which do not have their own databases. They use a combination of individual search engine?s information simultaneously, from a single site and using the same interface. Meta-searchers provide a quick way of finding out which engines are retrieving the best results for you in your search. There are two ways that Meta-searchers show their results. Most use a single list which display multiple-engine search results in a single merged list and had removed all the duplicate entries from the list. The second way that they display their results is through multiple lists. These are separate lists in which are displayed as they are received from each engine leaving the duplicate entries on the list.
