As a researcher you will be looking beyond books and journals for information.
This page gives principles of searching which can be adapted and applied to most information sources.
Start with a goal which will at least include:
Databases offer various options to refine and structure your search. Use the limit to search Abstract for the most relevant articles.
When you search databases or the internet you are searching for WORDS not ideas.
Recreate your hypothesis into a series of keywords.
Databases, including internet search engines like Google, operate with protocols.
" " - parentheses are used for a phrase
"random breath testing"
AND - for a more specific search join multiple terms with AND
roads AND wildlife AND "sunshine coast"
OR - broadens your search when:
NOT excludes results, but should be used with care, best after an initial search has identified a group of irrelevant results
lions NOT football
NEAR, WITHIN, W/N Some databases give other options, such as NEAR or within.
NEAR finds a term close to another, while WITHIN specifies how close:
roads within 5 wildlife will find
"making roads safe for wildlife", "wildlife safety on roads", "safer roads for wildlife crossing"
NEAR or WITHIN searches are more flexible than phrase searches and return more relevant results than AND searches
