Web Search Techniques

Here is a sample workshop handout that you can use to help you search the Web more effectively.

Case Sensitivity

Some search tools are case sensitive. If you search using upper case letters, case sensitive search tools will only retrieve words in upper case letters. If you search using upper and lower case letters, case sensitive search tools will only retrieve those words. However, if you search using all lower case letters, even when searching acronyms and proper names, both case sensitive and non-case sensitive search tools will locate all possible word-case variations. Use upper, mixed case searching purposely to limit your results.

Search example
"chinese food"
"Consumer Education"

Retrieves
Chinese food for health
Vitamins found in Chinese food
Consumer Education tips
The History of Consumer Education

Does not retrieve
Food cooked Chinese style
Beginning consumer education
Consumer education for kids

          

The AND Operator

AND searches for all the words located anywhere in a document. AND limits your results. It is the default operator for most meta-search tools.

Search example
king AND dream

Retrieves
Dr. King and his Dream
M.L. King - I have a dream

Does not retrieve
Disney's Lion King
ML King biography
Dream states in psychology

          

The OR Operator

OR searches for some or all words present in a document. Think of an OR search and an "either/or/all" search. OR expands your results. It is the default operator for many search engines

Search example
king OR dream

Retrieves
Disney's Lion King
Dr. King and his Dream
Dream states in psychology
M.L. King - I have a dream
ML King biography

          

The NOT Operator

NOT eliminates words that must not be in a document. NOT limits your results and eliminates a lot of non-useful results.

Search example
king NOT dream

Retrieves
Disney's Lion King
ML King biography

Does not retrieve
Dr. King and his Dream
M.L. King - I have a dream

          

Word Stemming

Use an asterisk (*) at the end, or in the middle, of a full or partial word to search for all variants of that word. Word stemming expands your results, but in a very focused, useful way.

Search examples
woman*
wom*
wom* NOT womb*
wom*n
wom*n*

Retrieves
woman, womans, woman's, womanizers
woman, women, wombats, womb
woman, women's (not womb or wombat)
woman, women
woman's, womens'

          

Phrase Searching

Phrase searching searches for words (and only those words) in the exact order you type them. Phrase searching limits your results, but is sometimes too strict of a search and eliminates many valuable documents.

Search example
"chinese food"
"Consumer Education"

Retrieves
Chinese food for health
Vitamins found in Chinese food
Consumer Education tips
The History of Consumer Education

Does not retrieve
Food cooked Chinese style
Education for consumers
Beginning consumer education

          

The NEAR Operator

NEAR searches for words which are close to each other but not necessarily right next to each other, nor in the order typed. AltaVista allows you to specify the number of words that can be between words (Example: king NEAR/3 dream)

Search examples
chinese NEAR food
Consumer NEAR Education

Retrieves
Food for Chinese women
Chinese food for health
Consumer Education tips
Education for Consumer Safety

Does not retrieve
The Chinese secret to longevity and good health are light daily exercise and good food preparation.
Consumer awareness lessons and their role in both elementary and secondary education.

          

Nesting

Nesting searches for word variations with one search. Nesting expands your results, but focuses them at the same time.

Search examples
legitimate AND (theater OR theatre)
Canton NEAR (Ohio OR OH)
lesson* NEAR plan* AND (math OR art)
art AND ((New York) OR Chicago OR London)

Retrieves
History of the legitimate theater
London's Legitimate Theatre
Canton OH companies
A short history of Canton and Columbus Ohio
Lesson planning for math teachers
Art lessons, plans, and activities
The New York art gallery scene
Art and artists in London's Soho district
Chicago: the art of snow removal

          

Combining Search Operators

You can combine operators in many different ways to create focused results.

Search examples
king AND dream NOT burger NOT elvis
ohio AND college* OR universit*
Canton NEAR (Ohio OR OH)
lesson* NEAR plan* AND (math OR art)

Retrieves
Martin Luther King - I have a dream
The dream of Martin Luther King in the 1990's
Ohio college grads
College libraries (Ohio)
A short history of Canton and Columbus Ohio
Canton OH companies
Lesson planning for math teachers
Art lessons, plans, and activities

Does not retrieve
Win a dream date with Elvis, the king!
I dream of owning a Burger King restaurant
College and university libraries
Canton OR.. home of the Ducks
A physics lesson plan for homeschoolers

          

Other Search Techniques

Open an additional browser window so you can search in one, and work in the other, while your search tool is retrieving results.

Use the "subject heading" technique to help you locate websites on a specific subject, or to help you limit the number of results your search retrieves. For example, combining two phrases "Chicago Bulls" and "basketball team" (which is the subject heading that would describe the Bulls) eliminates information about the arena where the team plays, as well as results related to the Chicago stockyards and bulls as animals.

Another library-related technique is corporate entry. Using the corporate entry for a group or person, rather than the common name, will help you locate official information more quickly, while often eliminating information created by others about the person or organization. For example, the official name of the Cleveland Indians is the Cleveland Indians Baseball Club. Use it to locate the official team page very quickly. This search also eliminate many fan pages and other sources of information that might not be authoritative.

If your results are in a foreign language you may be able translate them to English using AltaVista's translator which converts webpages from Italian, Spanish, French, German, and Portuguese into English (and vice versa).
