4. Internet Search Keywords
Operator
How it works
“ ”
When a phrase is put in “ ” then the search engine will only return links that contain the exact phrase. For example a search of I have a dream finds 315,000,000 sites, but a search for “I have a dream” finds only 2,150,000 sites and all those are related to Martin Luther King speech. +
Forces the search to include that keyword. -
Forces the search engine to exclude words. For example a google search for pets finds 162,000,000 sites, but if I don’t want anything on cats or dogs I put pets –cat –dog I get 31,600,000

5. Internet Search Keywords
Operator
How it works
AND
AND is the default if you put 2 or more terms in the search. A search for dog cat or a search for dog AND cat gives only pages that contains the word dog and the word cat. Google finds 64,600,000 sites OR
OR requires at least one of the terms joined by it to appear somewhere in the document. A search for dog OR cat finds 5,850,000,000 sites
AND NOT
AND NOT excludes documents containing whatever follows it. A search for dog AND NOT cat should find pages with the word dog but excluding the word cat. Google does not support the AND NOT command but rather changes it dog -cat

6. Examples
To search for a twins support group in Minnesota, but not return pages relating to the Minnesota Twins baseball team:
twins support group Minnesota –baseball
To find pages that include either “Tahiti” or “Hawaii” or both terms
Tahiti OR Hawaii
To find Islands in the Caribbean but not Jamaica
+islands + Caribbean -Jamaica
