7. Wed 18 Aug S. Dekeyser The Second Biggest Mistake Using the wrong tool at the wrong time

8. Wed 18 Aug S. Dekeyser Three questions Where would you find the telephone number or address of the Bama Six theatre? Where you would find the definition of the word “pestilence?” Where would you find the name of the war that the Treaty of Westphalia ended?

9. Wed 18 Aug S. Dekeyser What would happen if you tried to look up the definition of the word “pestilence” in the telephone book?

10. Wed 18 Aug S. Dekeyser YAHOO ISN’T A SEARCH ENGINE!... it is a directory.

11. Wed 18 Aug S. Dekeyser Directories Usually human- compiled guides to the web, where sites are organized by category Major directories: –MSN –Yahoo –Netscape ODP

12. Wed 18 Aug S. Dekeyser What directories are good for “What is the Web page address for some company, organization, or entity?” (or “who makes product X?”) “Where can I find a list of Web pages that focus on a particular, ‘universal’ topic?” In other words, directories are GREAT for “telephone book” searches.

13. Wed 18 Aug S. Dekeyser What directories AREN’T good for Directories are horrible for “encyclopedia” or “dictionary” searches. The only exception is if the topic is so universal that the directories have no choice but to link to a page or two that discuss that topic (and even then the selection will be slim.)

14. Wed 18 Aug S. Dekeyser Directories v Search Engines Directories are –human-compiled and –have a small number of pages in their databases (usually in the low millions) Search engines are –machine-compiled and –have a HUGE number of pages in their databases (usually in the hundreds of millions or even the billions)

15. Wed 18 Aug S. Dekeyser The Third Biggest Mistake Not knowing how to use directories or search engines to actually FIND stuff

16. Wed 18 Aug S. Dekeyser Search engine rule #1 Be specific... because if you aren’t specific, you’ll end up with a bunch of garbage!

17. Wed 18 Aug S. Dekeyser Search engine rule #2 Use quotes to search for phrases. “the tide is rising”

18. Wed 18 Aug S. Dekeyser Search engine rule #3 Use the + sign to require. “the tide is rising” +book

19. Wed 18 Aug S. Dekeyser Search engine rule #4 Use the - sign to exclude. “the tide is rising” +book -drugs

20. Wed 18 Aug S. Dekeyser Search engine rule #5 Combine symbols as often as possible (see rule #1). “the tide is rising” +book –drugs +climate

21. Wed 18 Aug S. Dekeyser The five rules 1.Be specific... because if you aren’t specific, you’ll end up with a bunch of garbage! 2.Use quotes to search for phrases. 3.Use the + sign to require. 4.Use the - sign to exclude. 5.Combine symbols as often as possible (see rule #1).

22. Wed 18 Aug S. Dekeyser Part Two: More Stuff No One Tells You Google’s shocking secrets revealed!

23. Wed 18 Aug S. Dekeyser Part Two: Contents Google’s Boolean default is AND. Capitalization does not matter. Google has a hard limit of 10 keywords. Google ignores a BUNCH of common words. Google does support wildcard searches … sort of. The order of your keywords matters.

24. Wed 18 Aug S. Dekeyser Google’s Boolean Default is AND But there are ways to get around that.

25. Wed 18 Aug S. Dekeyser Boolean Default is AND If you search for more than one keyword at a time, Google will automatically search for pages that contain ALL of your keywords. A search for disney fantasyland pirates is the same as searching for disney AND fantasyland AND pirates But, if you try to use AND on your own, Google yells at you. yells at you Source: http://www.google.com/help/basics.html

26. Wed 18 Aug S. Dekeyser Boolean OR Sometimes the default AND gets in the way. That’s where OR comes in. The Boolean operator OR is always in all caps and goes between keywords. For example, an improvement over our earlier search would be disney fantasyland OR “pirates of the caribbean” –This would show you all the pages in Google’s index that contain the word disney AND the word fantasyland OR the phrase pirates of the caribbean (without the quotes) Source: http://www.google.com/help/refinesearch.html

27. Wed 18 Aug S. Dekeyser Capitalization Does NOT Matter The old AltaVista trick of typing your keywords in lower case is no longer necessary.

28. Wed 18 Aug S. Dekeyser How Insensitive! Google is not case sensitive. So, the following searches all yield exactly the same results: disney fantasyland pirates Disney Fantasyland Pirates DISNEY FANTASYLAND PIRATES DiSnEy FaNtAsYlAnD pIrAtEs Source: http://www.google.com/help/basics.html

30. Wed 18 Aug S. Dekeyser Google’s 10 Word Limit Google won’t accept more than 10 keywords at a time. Any keyword past 10 is simply ignored. How can you get around this limit? Well, first you need to remember that … Source: Google Hacks, p. 19

31. Wed 18 Aug S. Dekeyser Google Ignores a BUNCH of Common Words Words to avoid

32. Wed 18 Aug S. Dekeyser Stop Words To enhance the speed and relevancy of your Web search, Google routinely and automatically ignores common words and characters known as “stop words.” Source: http://www.google.com/press/guide/reviewguide_7.html

33. Wed 18 Aug S. Dekeyser Stop _ _ Name _ Love This is certainly not a canonical list, but here are 28 stop words I know about. a, about, an, and, are, as, at, be, by, from, how, i, in, is, it, of, on, or, that, the, this, to, we, what, when, where, which, with You can force Google to search for a stop word by putting a + in front of it (for example pirates +of +the caribbean ) Source: 10/23/02 post by Bill Todd to news:google.public.support.general

34. Wed 18 Aug S. Dekeyser Dealing with the Word Limit Omit the stop words in your search terms and you’ll probably never run into the 10 word limit. Another way around the limit is to use wildcards. Image source: http://www.alloyd.com/

35. Wed 18 Aug S. Dekeyser Google DOES Support Wildcard Searches … Sort Of. When you wish upon a *.

36. Wed 18 Aug S. Dekeyser Wildcards Wildcards are characters, usually asterisks (*), that represent other characters. Google offers full-word wildcards. For example, if you search Google for it’s +a * world, Google shows you all of the pages in its database that contain the phrase “it’s a small world” … and “it’s a nano world” … and “it’s a Linux world” … and so on.

37. Wed 18 Aug S. Dekeyser it’s +a * world The + before a is required because it is a stop word and would otherwise be ignored. Most of the hits are phrases because that’s what Google looks for first. Oh, and I defy you to get that song out of your head! Image source: http://themeparksource.com/

38. Wed 18 Aug S. Dekeyser Wildcards and the Word Limit Remember when I said that one way to get around the 10 word limit was to use wildcards? Google doesn’t count wildcards toward the limit. For example, Google thinks that though * mountains divide * * oceans * wide it's * small world after all is exactly 10 words long. Source: Google Hacks, p. 19

39. Wed 18 Aug S. Dekeyser The Order of Your Keywords Matters A me life for pirate’s?

40. Wed 18 Aug S. Dekeyser How Google Works When you conduct a search at Google, it searches for –Phrases, then –Adjacency, then –Weights. Because Google searches for phrases first, the order of your keywords matters. Image source: Google Source: Google Hacks, p. 20-22

41. Wed 18 Aug S. Dekeyser For Example A search for disney fantasyland pirates yields the same number of hits as a search for fantasyland disney pirates, but the order of those hits – especially the first 10 – is noticeably different.

42. Wed 18 Aug S. Dekeyser Part Two: In Summary Google’s Boolean default is AND. Capitalization does not matter. Google has a hard limit of 10 keywords. Google ignores a BUNCH of common words. Google does support wildcard searches … sort of. The order of your keywords matters.
