What is a search engine? How do they work?
A search engine is like a huge world ‘Index’. You use it to look up Internet sites located around the world. You can search using key words. For example. If you wanted to search for a dressmaker in Melbourne who specialised in eveningwear you would type in ‘dressmaker Melbourne evening’ and you would get a list of web sites to visit (known as ‘search results’). You can then click on the addresses and be taken straight to the site. Each search engine works differently. Some scan for information in the title or header of the document; other’s look at the bold ‘headings’ on the page for their information. The fact that search engines gather information differently means that each will probably yield different results. Therefore, it’s wise to be registered with more than one search engine.
