Searching Techniques

Although you can find article citations in a database easily, finding useful and relevent articles is often difficult. Several search strategies will be useful.

Boolean logic uses and / or / not  to combine words or terms. 

Examples:    

bacteria or microorganisms          includes either term

microscopy and bioassay             includes both terms

turtles not migratory                      includes first term but not second term

 

Truncation symbol, usually the asterisk *; offers variant endings on words. 

Example: hypothe* retrieves hypothesis, hypotheses, hypothetical, etc.

 

Wildcard symbol, usually the question mark ?, replaces a letter or letters in the middle of a word or one letter at the end of a word. Not all databases allow wildcards.

Example:  

genetic? Retrieves genetic or genetics

colo?rful Retrieves colorful or colourful

 

Phrase searching, to keep words together as a phrase, you usually use the quote marks around the phrase "words together"

Example:  "global warming"

 

Author Name - the same author may publish under versions of a name over a lifetime. Search for different combinations of the name OR with unusual last names try searching for last name, first initial with an asterisk, as in Buffo J*

Examples: 

Silander, John A.

Silander John Augustus

Silander J.A.

Silander J.
