#)Enter terms to search
#)Use quotation marks to

11. Boolean Searching - AND
president Washington
Enter words connect with AND - it will
include sites where both words are found
Uses: joining different topics
(ie. “global warming” AND California)

12. Boolean Searching - OR
dogs cats
Enter words connect with OR - requires at
least one of the terms is found
Uses: join similar or synonymous topics
(ie. “global warming” OR “greenhouse effect”)

13. Boolean Searching - NOT
Washington School
#Enter words connect with NOT – searches for the first
term and excludes sites that have the second term
#Uses: join similar or synonymous topics
(ie. Washington NOT school)

14. Boolean – (Nesting) and Near
*In a string of searching, terms placed in
parentheses are searched first
*Parentheses must be used to group items if
there is another Boolean operator being
used
*NEAR may be used to require words to be
found within 16 words of each other in the
pages returned

15. Question Searching
• A question may be entered
in the search field of a
search engine.
• Ask Jeeves is a search
engine that encourages the
use of question searching

16. Advanced SearchingAdvanced Searching
#Advanced search features are
offered on many engines by going
to an “Advanced Search” page and
making selections
#This is effective in narrowing
search returns to a specific topic
or phrase
Google Advanced Search

18. Google Search Tolls
 Google also provides easy-to-use search tools. For
example:
 "Weather Chicago" yields the current weather in
Chicago
 "25 kilometers in miles" converts kilometers to miles
 "Define screen magnification" yields definitions for
screen magnification
 "Seafood restaurants 33716" yields restaurants that
serve seafood in or near that zip code

19. Keep It Simple
*Keep your search simple and web-
friendly. Start by entering one or two
words, and gradually adding relevant or
important words, if you’re unsatisfied
with the results. Less is more for a search
engine; meaning the less words you
query for, the more results the search
engine provides as output.
*For example:
*Query: [who is the president of america]
*Better query: [president of america]

20. #[word]
*Using the ‘#’ before a word
enables you to search for
hashtags in Google+, Twitter,
and more social networks.
*For example: [#privacy]
@[Social ID]
*You can search for social
accounts associated with a
person’s name by putting the
‘@’ sign before his/her name.
*Forexample: @[SadAdnanBa
ngladeshi]

21.  Search For Numbers In A Range
 You can tell Google to search within a range
of numbers, such as dates, prices, and
measurements. Using two periods (dots)
between two numbers makes Google search
within that number range and skip other
results.
 Using two periods after a number indicates a
lower minimum (number..) while putting it
before the number indicates a higher
maximum (..number). Type your search query
in the format of
[firstNumber..secondNumber otherWords] to
search between a specified lower and upper
bounds.
 For example:
 [android phone $300..$500]
 [television 20..50 inches]

22. Search Using File Types
*You can tell Google to search for a specified type of
file for your query. Usingfiletype operators before a
type of file tells Google to search only for specified
file types and skip other files. Type your search
query in the format of [filetype:type otherWords] to
search for a specific file type.
*For example: [filetype:pdf free photoshop books]
*:.pdf , :.docs , :.pptx , :.mp4 etc .
