Searching databases
Step 1: Analyse your topic for its main concepts
For example, your question is:The main concepts are global warming, water supply, and Australia
Find out more about Topic analysis in Module 4, Academic writing.
Step 2: Decide on the keywords you will use as search terms
For this topic there are three concepts so your keywords or phrases could include:
Concept 1: global warming, climate change, climatic change
Concept 2: rainfall, water, drought
Concept 3: Australia, Australasia
Step 3: Use Boolean logic when you are searching
The Boolean operators, AND, OR and NOT, have special functions when they are used between search terms.
Your database search could be typed like this:
Climate change and water and Australia
or, for even more references:
(climat* change or global warming ) and (water or drought or
rainfall) and Austral*
Note: * is a truncation symbol that will search for everything starting with climat* including: climate, climatic
Read more about Boolean searching and using truncation in the following guide Using boolean operators (pdf).
