1. 1 Internet Search Tools Adapted from Kathy Schrock’s PowerPoint entitled “Successful Web Search Strategies” Kathy Schrock’s complete PowerPoint available at: http://school.discovery.com/schrockguide/shows.html

2. 2 What are Internet search tools? Tools that help you locate information and Web-sites on the Internet Search engines Subject directories Meta search engines

3. 3 What is an Internet search engine? A search tool that will search for sites containing words that you designate as a search term. Search engines search their own databases of information

4. 4 How does a search engine work? Deploys a robot program called a spider or robot designed to track down Web pages, follow the links these pages contain, and add information to their own database Each search engine has its own way of organizing and displaying your results

5. 5 How do search engines differ? Different databases are searched The degree of detail collected differs The level of sophistication of the “robot” differs Relevancy rankings differ

6. 6 How does a search engine know about documents on the Web? If the search engine “spiders” or “robots” find the site on their fact gathering missions If the publisher of the document registers it with search engines (sometimes this is done for a fee)

7. 7 Search engine example Google

8. 8 What is an Internet subject directory? Organizes sites by subject Users work down a series of menus Smaller than search engines Maintained by humans

9. 9 Subject directory example Yahoo

10. 10 Which is better, a search engine or subject directory? Personal preference Directories allow the user to form the search, but may not use common terms Search engines allow the user to use common language, but may lead to lots of hits

11. 11 What is a “meta” search engine? A meta search engine doesn’t create its own database of information It searches databases of other search engines Allows you to sift and see what is out there. Example - DogpileDogpile

12. 12 How do I prepare to search? Formulate your question carefully Identify keywords Select synonyms and other word forms to refine your search

13. 13 How do I improve my use of search tools? Read the help files Use wildcard searches teen* (picks up teenage, teenagers, or teens) Use Boolean search techniques AND, OR, NOT to focus or broaden your search

15. 15 How do I determine if my search engine meets my needs? How easy was it to figure out how to search? Were the help files adequate? Were the amount of results adequate/overwhelming? How current were the results? What else makes it good? (...Any unique features? How are results organized?)
