2. Know synonyms and varied spellings

3. Know how to widen or narrow your search

4. Know some Web Searching Basics 5. Learn to use one or two search

There is a world of difference between searching

“Hate Crimes” and

“Anti-Hate Crime Legislation”

Know synonyms and varied spellings

“Hate Crimes”

are often also called “crimes that violate

civil rights” or

“Civil Rights Violation Crimes”

With some topics, know alternative spelling—

color might be colour

theater might be Theatre

The right “search phrase” can make a world of difference

“cutaneous anthrax” Produced 7 hits in .17 seconds on Google

Prioritize the terms in your search phrase

Some search engines will produce results by word order, with the first term being most

important

“Atlanta zoo” +pandaspandas +“Atlanta zoo”

could produce different results on some search engines that search

by word order

Other tricks to know when searching

Use lower case when searching Example: ibm, imac, nato

Use multiple words to narrow searchExample: “great lakes” and shipping

Use similar wordsExample: lesson, tutorial, class, seminar

Use plus and minus signs for “and” and “not”

Use a combination of “tricks”

Examples"marine mammals" –whales

computers workstations +network +security
