Working aspects of Search Engines

Search engines are the programs which enable users to search for any information or details on World Wide Web. The effective search engines maintain the real time information with the updated mix of images, web pages and other type of files. There is no doubt that the most effective searchengines are Google, Yahoo and Bing which work on 100% relevancy and congruity. 

Can you imagine what will happen if the whole system of search engine stops working at an instance? It is hard to clarify that the whole work ranging from marketing and internet to IT and business fields will shaken down.

The urgent need of Search engine is determined when the user typically search results for any particular query and wend his way through the results by just clicking on. He explores number of documents before finding exactly what he seeks.

The question arises now that how the search engine works? Is there any special mechanism behind its working? Yes, search engine basically works on two major functions: crawling and indexing.

Crawling of search engines is nothing but the movement of web pages through the interconnected links to billions of interconnected web documents. The next step of search engine is to analyze the content of each page for indexing process in which the web pages are successfully added on the search engine.

The process of indexing is required when the user searches for the required query on a particular search engine. Indexing allows the user to access the data which is stored on search engine servers.

Search engines are basically known as answer machines. It is due to the fact that when an user performs an online search then the search engine generally performs two activities: at the very first, search engine finds the relevant data as per the needs of the user and secondly, it puts the results on ranking basis which is set according to the popularity of the web sites. In this way, both the qualities of Search Engine are influenced by its working process.
