Searching Using Boolean!

Name: Elisabeth Wertheimer
Search: fall – “googled” on it’s own there were 1,620,000,000

Search Keys
Purpose of limiter
What did you find when you tried it? Was this limiter effective?

How many Hits?
AND
Narrows search – will find webpages where both words occur
fall and autumn
Very effective, narrowed the search down significantly to the season referred to.

223,000,000

OR
Expands search – will include webpages where either word occurs
 fall or autumn
Interestingly narrowed the search down more. Similar webpages as the “and” search.


132,000,000
NOT
Narrows search—will find webpages with first word but not the second.
fall NOT autumn
Not effective in narrowing down the search (still included both fall and autumn in the webpages)
223,000,000
“                    “
Uses phrases to search for.
“fall”
This expanded the search since both the verb and slang for “fall” was included along with the season.
1,630,000,000
*
“Wildcard” – allows for various endings
fall*
Expanded the search significantly for similar reasons as the quotation marks

5,900,000,000
- (minus)
Words connect with the should not appear
fall –autumn
Very effective, excluded all webpages associated with the season (much more effective than using “not”)
3,200,000,000
+ (plus)
Expands search – with include words in webpage search
fall +autumn
Similar to “and”, this narrowed the search down, with webpages focusing on the season.


224,000,000




5 Others Searches I’ve Found:

Effective in yahoo.com in comparison to google – webpages contained the word “fall” but did not refer to the season.
