Using Search Engines


1 Search engines other than Google are Yahoo, Dog pile, Ask Jeeves, Windows Live and more e.g. http://www.google.com/, http://www.yahoo.com/, http://www.altavista.com/ and http://www.alltheweb.com/
2 Problems that people may encounter are the large number of results that show up after a search, its not listed for academic results so any one can put a page on the internet, and there is a large number of factors that can effect the results of a search.
3 Strategies that can be used to over come these problems are using keywords, brackets around your search, using databases etc.
4 Boolean searches allow you to narrow down your search and can bring back results that are more relevant to you. Words that are used to do this are “and”, “or”, “not” and “near”.

During the class on UPC0004, Week 5, we learnt how to use search engines effectively along with a bit of basic information. We learnt that there were 3 main categories on the web. These included The Free Visible Web which will come up as soon as you type your search in Google, The Free Invisible Web, which is websites, and databases which you will require an email or URL address, and the Paid Databases over the Web which are the websites that require subscriptions and payment to access information.
Search tools come into 2 main categories. These are Search Engines and Directories.
Search engines look through databases and bring back results. Directories put information into relevant topics and are hand picked therefore will only require information that that is in the same topic and will all be academic.
Some examples of directories are:
- http://directory.google.com/
- http://dir.yahoo.com/
- http://www.looksmart.com/
- http://www.about.com/

During out tutorial we read the readings such as “Web Search Strategies”, “History of the Internet”, and “Search Engines Optimization for Companies”.
They provided information on the visible, invisible and paid databases on the web, search tool types and information on how to get the best search site, history of the web, how information is found, directories, search engines and data bases with a lot more.
It also offers graphs and pictures for the reader to look at and observe.
