Editor's Notes
- #3 A SEARCH engine is software designed specifically to allow you to find anything you want on the Internet. There are many search engines available. All you need to do is pick the one that you would like to use, insert the search string (what you are looking for) and start the search. You will get back a list of entries matching your entry and then all you need to do is double click on the lines that interest you and you will be taken to that homepage. Meaning of Crawling: (computing) index linked files or web sites, e.g. so they can later be searched

Tip 1: Use the ‘advanced search’ option with ALL search engines to refine your search Tip 2: Become familiar with your search engine by looking at the ‘Advanced Search Tips’ page
