One could mention, at some point, an overabundance of information. In 1999 there were over 800 million documents on the web. Sites commercial, personal, institutional, academic articles, novels, advertising pages, catalogs. More than 100 languages. It is enough to look, for example, “ancient history” and confuse you right away. Google has known only in a few years, a phenomenal success.
Launched as a simple engine test phase in September 1998 by two Stanford University students, Larry Page and Sergey Brin, search engine inaugurate its commercial version a year later. Google receives every day about 130 million applications worldwide because it is not a search engine like all the others. Even if based on search keywords, ranked according to the number and sites of origin, Google’s principle is that those sites pay to be shown on top. The “page rank”, invented by two students, is the popularity of the page.
Another peculiarity is its strategic ones: while other engines are invaded by dozens of banners on Google, advertising is limited to a few links hypertext discreet on-screen unless you are in relation to the information sought . Also, another feature is functioning in multiple languages. Perhaps even more exaggerated: Hungarian, Serbian, Ukrainian, Turkish, Russian, Polish, Dutch etc.
Since competition in this area is becoming increasingly fierce recently, Google held a contest whose prize was $ 10,000. The winner has created a way that allows you to search by geographic area in which pages are located. But the real winner of the contest can be even as Google has improved its search technology programs received from participants and they can manage liking because conditions in the forms included in the contest. Thus, technologies that Google has received relates to reducing errors in terms of pages created the possibility that hyperlinks are connected better when the target website changes its location, search for information in compressed files etc.
Also, Google has launched two sites to develop experimental search and navigation technologies. Home test, Google Labs, allows users to test new technology products research and development team of Google. These experiments include a glossary, an application of voice search, keyboard shortcuts for browsing search results. The second page shows the add-ons experimental toolbar’s Google, a download of software that allows users to surf the Web with the browser Internet Explorer from Microsoft to search the Google database through an application persistence included in interface internet Explorer. So currently, Google has the best search engine.
WebCrawler is the first of search robots being launched. Developed under a research project at the University of Washington in early 1994, was a real commercial success. Since the beginning of its operation, its database contained information on 6,000 web servers. At the end of the service received more than 15,000 requests per day. Basically, a robot is composed of three distinct modules; an explorer robot (spider), a system of indexing and searching program (searcher). The portals offer the ability to search the web is going through a directory or by a motor.
As a definition, a portal is a website that offers Internet users a wide range of resources and services. With it, you can find all the information they are looking for and even those that are not looking like the last quotation on the stock exchange, foreign affairs, domestic, economic, sports, social, time management box e- mail, horoscopes, etc. The best example of a search tool became portal Yahoo is even.
