Key to searching databases structuring your search effectively. You can't just type in your question or topic directly into a database and expect to find relevant results.
You need to search using terms from each concept of your topic and then combine these concepts together to retrieve your final result.
Let's use the following PICO as an example:
Patient / Population / Problem
children, infants, minors, paediatric
exercise, physical activity, exertion, sport, walking, swimming, aerobics, fitness, cycling
diet, nutrition, eating habits, food, feeding
obesity, overweight, weight gain, body mass index, BMI
Your search will need to contain the search terms from each of these concepts e.g.:
Platforms like EBSCOhost and Ovid let you search for different keywords using multiple lines of search boxes and to save these searches as you go along.
Perform a separate search for each concept of your topic:
Each search you make will be added to your Search History. Combine all of these searches together using the AND operator:
to get your final result:
You can also search for your terms all at the same time using AND and OR simultaneously:
Other databases may only give you one line to perform your search. If this is the case surround the different concepts of your search in brackets and combine each concept with the AND operator e.g.:
There are a number of other tools and techniques available to enhance your searching - see the Search Techniques.
