How Do I Chose

Before you begin searching create lists of keywords that describe your topic. 

Use a thesaurus to stimulate your word choice.

Generate synonyms for the concept. 

Use search engines that provide a list of related terms along with the results of your first search.

Sortfix

Key Words

Use the professional vocabulary of the subject you are investigating to create keywords.

Choose words that are unique and descriptive.

Look in the documents returned by the first query.

Upper and lower case

Spelling

Advanced Strategies

Scan for Additional Keywords

Some engines give more weight to the first keyword in a query.   

Try varying the order of keywords. Example: Which keywords will return the most

hits: blues music or music blues

Word Order

Hits are returned and ranked according to-- ◦ How many times terms appear on the page◦ How often terms appear◦ How close terms are to each other◦ How near the top of the page the terms are found

The best results will appear on the first page or two of hits

No two search tools are alike. Try another search engine, or rephrase your terms if you don’t get good results.

Hits

A query is made up of the keywords that describe your topic and the arrangement of those keywords using operators that focus the retrieval process.

Query

ANDRequires all terms to appear somewhere in the document, in any order. Example: curriculum AND high AND school

+Requires all terms to appear somewhere in the document, in any order. Example: +curriculum+high+school

" "Requires all terms within the quotation marks to appear in the order written. Creates a highly specific phrase. Example: "high school curriculum"

NOTExcludes documents containing whatever follows it.Example: high school curriculum not .com

-Excludes documents containing whatever follows it.Example: high school curriculum-.com

ORIncludes any page with at least one of the terms. Example: high OR school OR curriculum
