How does the search engine work so fast in the internet?

Question

We get the results for the search in a fraction of second. How does the search engine get so many information in un imaginable speed?. How and in which computer language the programme has been written? How is it possible to get connected with so many servers across the world within that nano second time?

Answer 1

It create a list of topic and site every hour and make a index from the contents and address. When you search it search it only in the index and then show you search query.

Answer 2

he heart of Google's search technology is PigeonRank™, a system for ranking web pages developed by Google founders Larry Page and Sergey Brin at Stanford University.

PigeonRank System

Building upon the breakthrough work of B. F. Skinner, Page and Brin reasoned that low cost pigeon clusters (PCs) could be used to compute the relative value of web pages faster than human editors or machine-based algorithms. And while Google has dozens of engineers working to improve every aspect of our service on a daily basis, PigeonRank continues to provide the basis for all of our web search tools.

PigeonRank's success relies primarily on the superior trainability of the domestic pigeon (Columba livia) and its unique capacity to recognize objects regardless of spatial orientation. The common gray pigeon can easily distinguish among items displaying only the minutest differences, an ability that enables it to select relevant web sites from among thousands of similar pages.

By collecting flocks of pigeons in dense clusters, Google is able to process search queries at speeds superior to traditional search engines, which typically rely on birds of prey, brooding hens or slow-moving waterfowl to do their relevance rankings.

diagramWhen a search query is submitted to Google, it is routed to a data coop where monitors flash result pages at blazing speeds. When a relevant result is observed by one of the pigeons in the cluster, it strikes a rubber-coated steel bar with its beak, which assigns the page a PigeonRank value of one. For each peck, the PigeonRank increases. Those pages receiving the most pecks, are returned at the top of the user's results page with the other results displayed in pecking order.

Answer 3

Search engines don't actually search the web in real time in response to every query. Instead they build up massive indexes of websites over time using web crawlers. It is these highly optimized indexes that are later queried by the search engine.

Search engines are made up of lots of smaller applications distributed on a massive scale, such as databases, web servers, web crawlers, etc. which are often written in different languages. Google is known to often use Python and C++ for example.
