Internet makes everything research work possible and easy. In just a click you will be redirected with different web sites that contain the information of the topic that you are studying. There are hundred millions of web pages in the World Wide Web that contains information on different topics.

When you are doing research you need a search engine to type the key word or phrase of the topic. After typing, the list of web page that contains the topic will be displayed on your screen. How are you going to identify which web page are you going to use? And what is a search engine?

Search engine is commonly used to seek for information available on the World Wide Web. The list results that can be found will be shown on your screen this is what we called the hits. Each result may contain the website address, information, and sometimes graphics.

Each search engine differs from each other on the way they operate. But in general search engines operates these tasks:

• Look for internet sites
• Save an index of the of the words and web sites found
• Look for words or phrase found in the index

Nowadays popular search engines will index numerous pages and respond to at least ten millions queries daily.

How search engine operates these major tasks?

Web crawling. When we say internet search engine it refers to World Wide Web search engines. A file must be found before the search engine can display the information. The process of searching information on numerous existing web pages can be done with spiders. As soon as the spider is creating a list, then we can say there is web crawling. These spiders must look a number of web pages so it could create and keep a helpful list of words.

The usual starting points of spiders' movement are record of top server or web pages. From here it will start indexing the words on the found page and on every link on that page. This will move quickly on other commonly used web sites.

Nowadays, Google is the most popular search engine for academic use. Google spiders record the words within the page and its address. It will index every important or key word on page. The idea of index is for faster process of searching information.

Meta Tags. Meta tags are commonly used to allow the web page developer to identify key words and concepts that will be used for indexing. It helps the search engine in deciding the correct meaning of the word. The use of meta tags describes the desire of web page owner or developer to include their page on the search engines actions.

What will be next after finding the information on web pages?

Once the spiders found the necessary information (but let me remind you that spiders never stops crawling), the search engine will keep those information be helpful.
There are some search engines that displays more that information and web sites. It also includes the number of times the word was indicated on a page.

When we mix proficient indexing and useful keeping of information we can expect quick search process.

Here are some of the commonly used search engines: Google, AskJeeves, Yahoo and MSN.
