Quick tips for searching databases


Library databases have a particular way of indexing and retrieving sources. When you enter a search, a database will attempt to find sources that contain the words you type in. 

To get the most relevant results, try these search tips. For more details, see the How to search databases guide
 

Identify concepts

What are the main ideas from your topic or research question?

Separate these as much as possible. For example, asthmatic children can be split into two concepts, asthma and children

Identify synonyms 

How might different authors talk about these concepts? What terminology might they use? 

You can also think of related ideas or examples. 

Truncate words

If you want to find words that share the same stem, you can do this by adding a symbol (usually an asterisk) to the stem.

e.g. educat* will find educate, educated, education, educational, etc. 

Lock phrases together

If you want to find a specific phrase, with words together in a specific order, you can add double quote marks around the words. 

e.g. "climate change"

Combine your search terms The above concepts and synonyms become your search terms - but you need to tell the database the combination of these words that you want. You can do this by using connectors, also known as boolean operators
AND

Use between different concepts

e.g. asthma AND children

OR

Use between synonyms. Group using round brackets.

e.g. children OR toddlers

Focus your search

Use filters or limits provided by the database.

e.g. by date, or type of source. 

Pro tip: Look for a link to help or search tips

Most databases will provide guidance on how to construct a search, including use of connectors and truncation symbols. 

AI alert: Artificial intelligence search features

Some Library databases offer the option to use artificial intelligence when searching. You might see something called Research Assistant or Discovery Assistant or natural language search

Using this, you can simply type in your research question or topic and the underlying AI model will figure out what you want - no need to think of synonyms or connectors. 

Keep in mind, though, that these systems are still relatively new and may not correctly interpret what you need. Look carefully at the results to see if they match your requirements - see the section on Evaluate, adjust, and improve your search below.
