==Search Engine==
A program that searches documents for specified keywords and returns a list of the documents where the keywords were found. Although search engine is really a general class of programs, the term is often used to specifically describe systems like Google, Alta Vista and Excite that enable users to search for documents on the World Wide Web and USENET newsgroups.
Typically, a search engine works by sending out a spider to fetch as many documents as possible. Another program, called an indexer, then reads these documents and creates an index based on the words contained in each document. Each search engine uses a proprietary algorithm to create its indices such that, ideally, only meaningful results are returned for each query.
There are basically three types of search engines: Those that are powered by robots (called crawlers; ants or spiders) and those that are powered by human submissions; and those that are a hybrid of the two.
Crawler-based search engines are those that use automated software agents (called crawlers) that visit a Web site, read the information on the actual site, read the site's meta tags and also follow the links that the site connects to performing indexing on all linked Web sites as well. The crawler returns all that information back to a central depository, where the data is indexed. The crawler will periodically return to the sites to check for any information that has changed. The frequency with which this happens is determined by the administrators of the search engine.
==Reaction==
Search engines are the key to finding specific information on the vast expanse of the World Wide Web. Without sophisticated search engines, it would be virtually impossible to locate anything on the Web without knowing a specific URL. But do you know how search engines work? And do you know what makes some search engines more effective than others?
When people use the term search engine in relation to the Web, they are usually referring to the actual search forms that searches through databases of HTML documents, initially gathered by a robot.

''THE 3 SEARCH ENGINES..ALTAVISTA,HOTBOT AND DOGPILE..
==Altavista==
it was one of the three largest and most important search engines for many years, but it is no longer as popular as it used to be. It had two distinct search modes: Basic Search and Advanced Search. In August 2000, it introduced a third: the Power Search. In Feb. 2002, the Power Search features were added to the Advanced Search page and then in Nov. 2002 were also moved to the More Precision page. There are some significant differences between the Basic and Advanced search pages, as will be seen below. In Feb. 2003, AltaVista was brought by Overture. Overture expected to merge the AltaVista and AlltheWeb databases later in 2003, but once Yahoo! bought Overture, AltaVista's database was replaced by a Yahoo!/Inktomi on March 25, 2004. Use the table of contents on the left to navigate this review.
Database:
AltaVista has a variety of databases:
Web database: AltaVista's own indexed Web pages including PDF files
Directory: Open Directory (formerly LookSmart)
News: AltaVista's own crawled pages (formerly from Moreover)
Ads: from Overture
Images: AltaVista's own crawled image files
Audio and Video: AltaVista's own crawled multimedia files
AltaVista has experimented with a variety of databases in addition to their regular Web page database. In the past, they have served results from Ask Jeeves, their own Usenet database, RemarqUsenet, Overture (formerly GoTo) ads, RealNames Internet Keywords, and Look smart categories. As of Dec. 2002, most of these additional databases are gone, except for the Overture paid positioning results which may appear at the top and bottom of results, labeled as "Sponsored Matches." AltaVista does have other databases available, including images, MP3/audio, video, directory, and News databases. In addition, there are the Altavista Shortcut which may show up at the top of regular search results. These provide quick links to selected popular information.
=== Hotbot===
HotBot, owned by Terra/Lycos, is one of older Web search engines. Originally it just used the Inktomi database and then added Derict hit and the Open directory. Then in Dec. 2002, it relaunched
as a multiple search engine with Inktomi, Fast, Google, and Teoma. In July 2003, they stayed with the same four databases, but renamed them HotBot, Lycos, Google, and Ask Jeeves. Lycos was dropped in March 2004. This review covers HotBot using the Inktomi database, which they now call "HotBot." See the Google and Teoma (Ask Jeeves) reviews for more details on how their database and interface work, bearing in mind that not all features are available at HotBot. The basic search screen shows no options, but choose Advanced Search for the full range of search features. To see how HotBot used to work, see the old Search Engine Showdown Review. Use the table of contents on the left to navigate this review.
HotBot offers the choice of three search engine databases:
* HotBot (which is actually a Yahoo!/Inktomi database, and the version reviewed here)
* Google
* Ask Jeeves (the Teoma database)
HotBot is one of the early Internet search engines and was launched in May 1996 as a service of Wired Magazine. It was launched using a "new links" strategy of marketing, claiming to update its search database more often than its competitors. It also offered free webpage hosting, but only for a short time, and it was taken down without any notice to its users. Though competitive when it was acquired by Lycos in 1998, HotBot has in recent years reduced its scope. Today the website is merely a front end for third-party search engines Yahoo.com, and MSN, as well as Lycos' own lyGo.com. It was one of the first search engines to offer the ability to search within search results. The site still exists, however it is run by Yahoo! mainly.
==Dogpile==
Dogpile is a meta-search engine that transmits a search simultaneously to several individual search engines and their databases of Web pages. The default list of search engines queried varies. You can also customize Dogpile to search specific search engines. Results are retrieved in lists of 10 hits from each engine queried. If more than 10 results are found, a link to the next list of hits is given. It is important to remember that meta-search engines only spend a short time in each database and may only retrieve a small percentage of any of the results in any of the databases queried.
Dogpile also for me is a best example of search engines for the reason that Dogpile fetches and ranks results from multiple search engines, letting you search for key word, pictures, audio, video, news,or phone numbers==Kartoo==
KartOO is a French-based meta search engine, and a delightful twist on searching! Although lacking in database size, KartOO shines with its graphical presentation. By using a visual "mindmap" to display its results, users can see how keywords branch out to specific hits. You can even customize how the map displays on your screen! If you're not in a hurry to do your searching, then try this beautiful Flash interface!::"Very cool!". "I love the mindmapping". "Excellent graphics". : KartOO is building a niche for itself. Watch for this service to become big within 3 years
==Ditto==
Ditto.com is a leading visual search engine. Ditto enables people to navigate the Web through pictures. It is far easier for people to find what they are looking for when they are looking at it! Pictures are fun, fast and intuitive.Our web site is a hugely popular destination for visual searching among all age groups, offering advertisers the opportunity to reach their audiences with targeted keyword or category placement.Reaction:We believe relevancy is the key difference in our technology and identify websites containing media via our automated crawler and have a Highly relevant results require on going maintenance

Working full-time at an internet company, Paulo spent his after hours working on a mobile MSN application. After several weeks, he won the bet and uploaded the application on a server. It was here that visitors asked if he could make a web version of the application. As user traffic spurred, Paulo decided to take the idea to the next level.On September 9th 2003, Paulo together with two partners created EverywhereMSN.com. Microsoft however claimed the domain name and shortly after on December 4th 2003 the domain was changed to e-messenger.net. On May 1st 2004, e-Messenger became incorporated.

The Skype Group has its headquarters in Luxembourg, with offices in London, Tallinn, Tartu, Stockholm, Prague, and San Jose.Skype has experienced rapid growth in popular usage since the launch of its services. It was acquired by eBay in September 2005 for $2.6 billion.One of the initial names for the project was "Sky peer-to-peer", which was then abbreviated to "Skyper". However some of the domain names associated with "Skyper" were already taken. Dropping the final 'r' left the current title "Skype", for which domain names were available.On April 24, 2008, Skype announced that they offer Skype on around 50 mobile phones.On October 29, 2007, Skype launched its own mobile phone under the brand name 3 Skypephone, which runs a BREW OS.

Official Skype support is available as part of X-Series together with mobile operator 3. However this uses a regular mobile phone call and iskoot to a Skype gateway, rather than mobile internet.
