Identify the main concepts of a topic
In order to find relevant articles, you must identify all important aspects (concepts) of your information need(s).
Here are some examples of questions to help you achieve this outcome:
Your answers to these questions must be short (single word or expression). If the topic of your search includes an original aspect, this should be reflected in your answers.
Connect the concepts with the "AND" operator
Generally, a subject can be represented using three concepts, yet this is not always possible. These concepts must describe and cover your information need.
To meet the information need Optimization of the winter maintenance activities of road networks, the articles retrieved by executing the search strategy should necessarily address the following three aspects:
Subject: Winter maintenance

This Venn diagram represents the Boolean logic applied to a subject. As shown by the red circle, the interesting articles are those found at the intersection of the three aspects.
