3. 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 |
You can search more broadly on macronutrient deficiencies that may result from the diet by adding these to your list. |
|
Cardiovascular disease |
cardiovascular 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 |

4. Where to search
Google Scholar can be a useful place to start looking for scientific evidence. The following video will step you through how to search:
Advanced Google Scholar search (1:21)
Ovid Emcare is a key database for health sciences and contains scholarly and peer-reviewed literature in nursing and allied health.
5. How to search in databases
In Ovid Emcare you will need to search each different concept one at a time.
Step 1
Deselect Map term to Subject Heading so you just do a keyword search.
Step 2
Enter your first concept into the search box. Use OR to connect any synonyms. Select Search.
Step 3
Enter your second concept into the search box. Again use OR to connect any synonyms. Select Search.
Step 4
Once you have searched for each of your different concepts you can combine them using AND to form your final search.
Step 5
Scroll down to see your search results.
Tip: You can use this method to search other databases like Medline and Scopus.
6. How to find systematic reviews
You can search for systematic reviews and meta analyses in these databases:
| Limit your search to systematic reviews in the database: |
|---|
- Search keyword systematic review as a third concept
Note: make sure to untick box Map term to Subject Heading - Use AND to combine all your concepts
| Note: with Ovid databases such as MEDLINE and Emcare, you may also use Additional Limits to narrow your Publication types to systematic review and meta-analysis (hold down CTRL key to select multiple items). |
- Search example in Scopus
| Note: In Scopus, use double quotation marks to search phrase. E.g. "paleolithic diet*" |
