1 Task 1

2 Know how to use keywords and search terms to search the internet Understand why it is a good idea to refine searches to reduce the number of hits returned Be able to search for information effectively, and comment on the trustworthiness of the sites

3  Internet search sites can search enormous databases of Web pages, using titles, keywords or text. You can maximize the potential of search engines by learning how they work, and how to use them quickly and effectively.  The challenge is to ask your question the right way, so that you don't end up overwhelmed with too many search results, underwhelmed with too few, or simply unable to locate the material that you need. As with most skills, practice makes perfect!

4  Before doing a search, it's important to define your topic as completely and succinctly as possible.  Write down exactly what information you're looking for, why you're looking for it, and what you're not looking for.  This will help you to discover the best keywords for your search.

5  The most powerful keyword combination is the phrase. Phrases are combinations of two or more words that must be found in the documents you're searching for in the EXACT order shown. You enter a phrase - such as "feta cheese" - into a search engine, within quotation marks.

6  Boolean" searching can narrow your search to a reasonable number of results, and increase the chance of those results being useful.  The three most commonly used Boolean commands (or "operators") are AND, OR and AND NOT.

7  AND means "I want only documents that contain both/all words."  For instance, the search "London" AND "Big Ben" AND "Buckingham Palace" AND "Trafalgar Square" would return only documents that contained all four keywords or phrases.

8  OR means "I want documents that contain either word; I don't care which."  The query "London" OR "Big Ben" OR "Buckingham Palace" OR "Trafalgar Square" would return all documents that contained even one of these four keywords or phrases.

9  AND NOT means "I want documents that contain this word, but not if the document also contains another word."  The query "London" AND "Big Ben" AND NOT "Buckingham Palace" would return documents that include London and Big Ben, but not those that also include Buckingham Palace.

10  It is sometimes called BUT NOT or NOT, and is sometimes indicated by placing a minus sign (-) before the term or phrase to be removed, eg

11  Using three search engines complete three different types of search.  Basic Search  Advanced Search  Boolean Search  Using the results from the above select and justify which search engine you will use

12  Explain/ describe the Research Topic.  Explain what the final report will contain  Explain who the final report is for.

13  State the three different types of search engine you will use.  For each one explain, very briefly how it works.  Explain that you will test each one to see which one gives you the best results for a:  Simple/ basic search  Advanced search  Boolean search

14  A basic search is where you type a criteria (phrase/ words) into the search engine.  Decide what you want to search for, i.e. for information about the MDG  Produce a table like:

15  Next, show the first two results for each and write underneath how useful the information is.

16  Include a screen shot of the three searches.  Don’t crop the screenshots!

17  All search engines have an Advanced feature.  You will need to use this to search for information. You can use the same criteria as you used in the last search.  Take a screen shot of all three advanced searches  Annotate the screen shot to state what you have changed

18

19  After the searches, produce the same two tables as for the Basic Search

20  All search engines allow you to use boolean operators to make more accurate searches.  Produce:  Screen shots of you using boolean operators in the three search engines.  The two tables you produced for the Basic and Advanced searches.

21  Sum up the results of the three different search methods using, Basic, Advanced and Boolean searches.  Chose on of them.
