How do Search Engines work?

Bluebirds discussed what search engines were today. They could name some such as Google, Chrome, Firefox and Bing. They watched a great explanation on BBC Webwise which explained how search engines were like a huge electronic library containing billions of pages of information. With books we use the index to find information quickly. To focus our searches we learnt how to refine our searches for more accurate results.

Kai – I found out by adding keywords you can find better results such as adding the word KIDS.
Kerris – You can use inverted commas to search for two keywords together.
Moharnab – You can add a dash to exclude certain information.

We also need to consider whether information found in a search engine is reliable and be aware that some companies pay to make sure their information is in the beginning of results found.
