11
Search Engines

• Single - Multiple Search Differences
• Single Search Engine
• A web site that will take a word or phrase that
  you provide and return web pages that correlate
  with the words given.
• Multiple Search Engine
• A web site that will take a word or phrase that
  you provide and then in turn give that out to
  multiple search engines and will format the
  results from all the different search engines
  onto a single page for you to view.

12
How Search Engines Work

• Spiders
• Computers that are constantly searching the
  internet for content.
• Usually a part of a large network of computers
  all searching for the same search engine.
• Each computer is searching its own (or new)
  section of the web, but sharing its results with
  the rest of the network.

13
How Search Engines Work

• Indexing
• Indexing is what happens to the information that
  the spiders retrieve from the internet.
• When a spider comes across a website that has to
  do with dogs, it then records the web address
  with a multitude of keywords that are associated
  with it. (dog, canine, etc.)

14
How Search Engines Work

• So when you do a search for the work dog, the
  search engine takes that keyword and compares it
  to the master index.
• Once it finds that spot in the index, it returns
  all the websites that have been correlated with
  the word dog to the screen where you can click
  on whichever link you like.

15
How to make search engines work for you.

• Boolean expressions
• AND
• OR
• NOT
• Limitations
• Keyword strategies
• Ordering Grouping
• When to be specific
• When to be general

16
Boolean Expressions

• AND
• This is to be used when you have multiple words
  that you need searched for.
• For Example reading AND writing
  will return websites that have to do with
  reading and writing, not just reading or just
  writing.
• Most modern search engines incorporate AND by
  default so you could simply type in reading
  writing instead of reading AND writing.

17
Boolean Expressions

• OR
• This is used when you want to search for a number
  of different topics.
• For Example reading OR writing
  will return websites that have to do with
  reading or writing, unlike AND which would return
  websites only if they had to do with both.

18
Boolean Expressions

• NOT
• This is used when you want to search for a topic
  that does not contain another keyword.
• For Example reading NOT writing will
  return websites that have to do with reading
  only, without any reference to writing.

19
Boolean Expressions

• Limitations
• Google and Multiple search sites will do a
  keyword search instead of a Boolean search even
  if you type in NOT.
• To get around this, you can either click on the
  advanced search link, or in Google use its symbol
  (-)
• Reading NOT writing reading -writing

20
Keyword Strategies

• Ordering Grouping
• Putting keywords in a specific order has a great
  deal to do with how results are displayed.
• Grouping keywords with quotation marks have a
  large impact on how many results are returned.
• For Example
• WASL reading test 20,700 results
• Reading WASL test 20,700 results
• WASL reading test 71 results
• Reading WASL test 8 results
• The first two, even though they have the same
  amount of results, are in a different order.

21
Keyword Strategies

• When to be specific
• For example if you search for current president
  of the united states, it will return results
  about George W. Bush.
• When to be general
• For example if you search for president, it
  will return results on the election, presidential
  candidates, past presidents, etc.

22
What do I do know?

• How to get a copy of the information.
• Different formats
• Printing
• Saving to disk
• Save website as a favorite. (bookmark)

23
Downloading Content

• Different File Formats
• .pdf Adobe Acrobat File
• .doc Microsoft Word File
• .html Standard Web Page
• All of these file formats will allow you to save
  and print.

24
Printing information

• This is the easiest way to make a copy of the
  information you find on the internet.
• This is usually as simple as going to File -
  Print
• If a .pdf is opened with Acrobat, there is
  usually a Print button as well.

25
Saving to Disk

• If you find information on the web that you want
  to keep permanently, you can save that page to
  your hard drive.
• This is usually accomplished by going to File -
  Save, then choosing a file location and name.

26
Copy and Paste

• Sometimes you get a website that will not allow
  you to print the section you want. Most of the
  time this is due to the fact that this website
  uses frames, and is printing the wrong frame.
• One way to print out the text on the page is to
  highlight the text you want to print, then go to
  Edit - Copy.
• Next, open Microsoft Word, or any other word
  processing program, create a new, blank document,
  and then go to Edit - Paste.
• What this does is paste the text from the webpage
  into a document that you can save or print.

27
Favorites and Bookmarks

• Finally, if you dont want to print, or take the
  time to save the web page to your hard drive, you
  can simply save that page as a favorite.
• This does NOT save the contents of the page on
  your computer. So if the page is changed, or
  gone, you are out of luck.
• This simply provides an easy way to get back to
  that page.

28
Favorites
29
Favorites

• To do this, simply go to Favorites - Add page to
  favorites.
• Now the next time you want to access that page,
  simply go to Favorites, and look for the name of
  the page.

30
Browser Types

• Internet Explorer
• Most widely used browser.
• The fact that this comes as the default browser
  on all Windows based computers, and most Mac
  based computers means that this is the browser
  you are likely using.
• Most widely supported.
• Most websites have all their pages optimized for
  Internet Explorer.

31
Internet Explorer

• However, due to the fact that it is so popular,
  people are constantly looking for ways to exploit
  weaknesses.
• To ensure your online security, you should check
  to see if your Internet Explorer can be updated
  at least once a week.
• Current Versions
• IE 6.0 Service Pack 1 for Windows
• IE 5.2.3 for Mac OS X
• IE 5.1.7 for Mac OS 8.1 - 9.2

32
Browser Types

• Netscape
• Not as widely supported or as popular as Internet
  Explorer.
• New versions feature tabbed browsing, which can
  be very handy when researching.
• New versions feature built-in pop-up blocking.
• Currently at Version 7.2 for Mac OS X and
  Windows.
• For Mac OS 9 and below users, use Version 7.02

33
Safari

• For Mac OS X, Apple designed an all new web
  browser called Safari.
• This browser features tabbed browsing and pop-up
  blocking just like Netscape.
• This browser also features a built in Google
  Search bar, which eliminates one step when doing
  research.
• This browser is for Macs with OS X only, and can
  be kept up to date using Macs built in Software
  Update.
