Exercise 1
How does Google “think” about your
searches?
Please pause and wait for discussion when
you reach a
A Close Look at Google
Search Results
• Excerpt of page with your terms
• Matched terms in bold
• Which Google database used
• Approx. # of hits
• Terms actually searched on, as Dictionary links
• URL, size, date last crawled
• Link to Cached copy
• Pages supposedly like this one
• 2nd page from
same site
• All Google pages
from this site
Don’t believe the number of Results
They are approximate, changing, and not comprehensive
Default Matching on Search Terms

Default AND between terms

Google takes a FUZZY approach




only some of the words if a page is “important”
words may occur only in pages that link to the page
words occur somewhere on the site a page belongs to
Cached reveals the page as Google found it



may differ from the current page
Cached exists if a page is full-text indexed
 About 1 billion pages in Google are not cached
 Not fully searchable
no Cached if a page owner requests not to be cached
How Can You Know
Why Google Found a Page ?

Click Cache link toward end of results

top area often explains what was matched
Stemming
 Google
stems “when appropriate”
automatically detects word stem or root
 retrieves with various endings

kite flying gets kite kites kiting
fly flying, flyers, flyer’s, flyers’

to turn off
+kite +flying
“kite flying”

single word searches not stemmed
Words Google Does Not Search

Common or “stop” words ignored
to be or not to be



no list of “common” terms
Google tells you below search box in results
to turn off

+to +be +or not +to +be
“to be or not to be”
single word searches possible on common words
Ranking of Results

Word order matters




favoring phrases (words together)
looks for phrases with something in place of
stop words
word repetition and proximity also count
Google ranking is a great mystery

PageRank combines many factors



popularity - links to a page and their importance
“importance” - a value of 0 (low) to 10 (high)
term placement - phrases, proximity, repetition
See Cheat Sheet #1

“FUZZY” Default AND

Problems with AND default:

words can occur anywhere in results pages




some pages may not contain all of your words
some may not have any of your words
Use quotation marks to require words together


may have different meanings or contexts
turns common words into unique search terms
“working mothers”

working mothers
2,680,000
“dry cells”
11,500
1% of
dry cells
1,010,000
Hyphen makes phrases and searches with and
without hyphens
bite-sized retrieves bite-sized, bite sized, bitesized
Force “FUZZY” with OR Searches

Singulars and plurals not covered by
stemming
parent OR parents

Equivalent or synonymous terms
parent OR guardian

Misspellings
libarian OR librarian

Apostrophes and their misuse
april's OR aprils OR april "fools day"
Ask Google to be “FUZZY”

Synonym search
~ immediately before a word

sometimes “thinks” of very broad, related terms
~food
~facts
~help


recipes, nutrition, cooking
information, statistics
guide, tutorial, FAQ, manual
Often: Terms appear in links pointing to a retrieved page
Take advantage of stemming
Let stemming handle variant endings:
“wild flowers” OR wildflowers hike “point reyes”
april OR may OR spring
hike, hikers,
hiking, hikes
Ask for “FUZZY” Number Ranges

Numrange search uses
. . (no spaces)
babe ruth 1921..1935
results have highlighted dates within this range
3..6 megapixels digital camera
most numbers will be associated with megapixels
DVD player $250..
can be open-ended -- any number above starting number
 The Whole-Word Wildcard:
Allowing FUZZY within “ ”

Can’t remember the exact wording in a phrase?
Who wrote something like, “The stag at night drank his
fill”?
Try searching:
“the stag * * * his fill” OR “the stag * * * * his fill”
ANSWER: “The stag at eve had drunk his fill” - in most sources
--Sir Walter Scott, “Lady of the Lake”

Construct proximity searches
Or
try GAPS
www.staggernation.com/cgi-bin/gaps.cgi
"george bush"
"george * bush"
"george * * bush"
"bush george"
"bush * george"
Excluding to Control “FUZZIness”
You want: Medical info about a pancreatitis
diet
 Start with: pancreatitis diet
172,000
 Eliminate undesirable words in results:

pancreatitis diet -cat -dog
132,000
pancreatitis -cat -dog -"support group"
128,000
Select exclusions carefully
Ask Google to be Very “FUZZY”:
Related & Similar

Two commands for the same function




click Similar at end of result
search related:www.infopeople.org
Sometimes hard to see how related

links to and from the target page

major words in and ranking of related pages
Possible uses

comparison shopping
find more sites like a site
related:www.econsumer.gov

use to evaluate a suspect page

Limiting to Find
the Hard-to-Get
Limiting: Words in <Title>

intitle:

finds pages concentrated on your term
hybrid cars intitle:mileage
hybrid cars mileage

with quotes:
intitle:”cuban embargo”
“cuban embargo”

7,060
296,000
581
28,000
with OR:
intitle:”global warming” OR intitle:”greenhouse effect”

Use allintitle: to require all words in title
allintitle: hybrid cars mileage

86
can combine only with site:
allintitle: hybrid cars mileage –site:com
11
Exploiting a Page’s URL

Limiting to domain (edu, gov, etc):
site:edu OR site:gov OR site:ca.us

complete list at:
http://en.wikipedia.org/wiki/List_of_Internet_TLDs

Searching within a Site

site:
site:memory.loc.gov lincoln “sheet music”



works only in top/first part of URL
omit http:// and final /
makes Google into a search engine for pages that are indexed
in Google

inurl: less specific

term may be anywhere in URLs
inurl:lincoln “sheet music”

finds “lincoln” anywhere in any URL and “sheet music”
somewhere in the pages
Limiting to Types of Documents

filetype:

OR to find more than one
form 1040 filetype:pdf - finds forms

-filetype:

exclude certain filetypes
form 1040 -filetype:pdf - finds help with forms

View as HTML link can be useful


avoids viruses a document might carry if opened
allows viewing without the software or reader
Caveats for Limit Commands

Cannot always be combined



link: similar: must stand alone
allintitle: allintext: allinanchor: allinurl: with site: only
You can mix all other limit commands, usually:
inurl:ucla intitle:admissions statistics
intitle:”thyroid disease” site:edu OR site:com

Be careful not to ask for the impossible:
site:ucla.edu -inurl:edu
site:com site:edu site:gov

Some require understanding HTML hypertext links:

inanchor:links looks for text in link tags in the HTML code:
<a href="http://www.pancreasweb.com”>Pancreatitis links</a>
<a href="www.pancreaticdisease.com/links/links.htm”>Links</a>

Finding Info on a Subject
Finding Directories & Link Lists

EXAMPLE - looking for links or directories about:
“women’s history” “middle east”

Use words likely to occur in link-list or directory pages
links OR "directory of" OR guide “women’s history” “middle east”
“what’s new” OR “what’s cool” “women’s history” “middle east”

<Title> field limit to focus pages you want
intitle:links OR intitle:”directory of” OR intitle:”encyclopedia of”
“women’s history” “middle east”
intitle:”women’s history” intitle:directory “middle east”

Are there agencies or organizations with links on this topic?
inanchor:links society OR association
"middle east" "women's studies"
Be creative. Substitute database for “directory” to find searchable databases
Google’s Directory

1.5+ million pages (compare with 8+ billion in web search)

DMOZ Open Directory


Google “importance” ranking within directory
EXAMPLE:

women's history middle east OR eastern
Click on useful subject categories for more:
Science > Social Sciences > Area Studies > Middle Eastern Studies
Society > People > Women > Women's Studies > By Topic
Society > Issues > Human Rights and Liberties > Regional > Middle
East
Search Google for Weblogs

Current commentary, opinions, misc. musings



Google indexes “important” blogs frequently
more than most web pages
Thorough search impossible
blog OR weblog OR “web log” your subject words
inurl:blog OR inurl:weblog your subject words

If you know the software a blog is using:
“powered by blogger” your subject words
site:blogspot.com your subject words
“powered by geeklog” your subject words

Try searching the Google Directory
Search Google Groups for Info

Usenet news groups back to 1981




archive of UNevaluated public thoughts, advice &
opinions
some not found elsewhere
select threads with more than one article for context
Search differences:



search for a group by name
search within a group
+ required for common words even in “ “
“hair loss” OR "loss +of hair" OR balding
group:alt.support.thyroid


use Advanced Search to limit by group or date posted
Create new mailing lists with registration
Google as Encyclopedic Glossary

Use the command define:[no space]


Google finds and ranks Web pages with definitions
define:internet
define:due diligence
Or build searches for pages with definitions:
internet “what is”
“what is the internet”
“internet stands +for”
internet ~beginners
internet ~FAQ

Also many common facts available:
population of japan
currency in algeria
birthplace of hitler

Thinking in Sync with Search Engines

Search engine balancing act:

Do we agree with Google’s “importance”?




tyrannical or democratic?

favors established more than new websites

favors trendy, high-speed, consumer, vroom & zoom
Are Google’s secretiveness & fuzziness trustable?
Have search engines changed us?

Do we accept “good enough” quicker?

Have we given up “thorough” and “certain”?
Will semantic & linguistic analysis help?

Or bring in a new age of “whatever” thinking
