    How to be a safe and smart SEARCHER

    S

    everal keywords will help to find better results. Use more than one keyword when you are doing a search. If you want to find out about seagulls, for example, search for and not just ‘seagull’ – because seagull might also be the name of just about anything else, from a hotel to a documentary film.

    E

    xact references can help you find what you’re looking for. If you are looking for an exact phrase or sentence, e.g. , type it between quotation marks (“”) and only exact matches will be shown. This is useful when you want to find something you’ve already seen but lost.

    H

    ave a filter（过滤程序）. It’s a good idea to filter your searches, especially when you are searching for pictures. Ask an adult to help you add a filtering system. There are lots of filtering software options available.

    E

    R

    eliability is very important when you are searching on the Internet. Always ask yourself, “Is this reliable?” Don’t make the mistake of believing everything you see. Some websites are unreliable and some information is false. Check your information on other websites before accepting it.
