Build your search

Before you start looking for information, use the following steps to plan your search:

1. Define any words you are unsure of.

2. Identify the main ideas (key concepts) in the statement. These will form the foundation of your search.

3. Make a list of any synonyms or related keywords for each key concept.
     Consider any:

  • word plurals - disease / diseases
  • different word forms - paleo / palaeolithic
  • different word spellings - palaeolithic / paleolithic
  • common acronyms - CVD / cardiovascular disease

For example:

Key concept Synonyms/alternative concepts Tips

Paleo diet

caveman diet
hunter-gatherer diet
paleo diet
paleolithic diet
palaeolithic diet
stone age diet...

You can search more broadly on macronutrient deficiencies that may result from the diet by adding these to your list.

Cardiovascular

disease

cardiovascular disease
CVD
heart disease
vascular disease

You can try searching on the relevant body part or system, for example heart, cardiovascular, blood vessel.  

4. Build your search. Use the connectors AND and OR to combine your concepts into different search strategies.

  • AND connects each different concept.
  • OR connects your synonyms (alternative terms).

For example:

  Building your search
Concept 1

paleo diet OR paleolithic diet OR caveman diet OR hunter gatherer diet OR stone age diet

  AND 
Concept 2 cardiovascular disease OR CVD OR heart disease OR vascular disease OR heart
