Final answer:
When using the portal search, you can include different combinations of search terms to narrow down your results. Generating a range of keywords and using boolean operators like 'AND' can help you find more specific and relevant sources.
Step-by-step explanation:
When using the portal search, you can include different combinations of search terms to narrow down your results. One way to do this is by using the 'AND' operator.
For example, if you are looking for sources that include both 'artificial intelligence' and '2019', you can search for 'artificial intelligence AND 2019'. This will help you find more specific and relevant sources.
Another tip is to generate a range of keywords for your search. Libraries and online databases use different search algorithms, so it's important to consider the specific key terms for each platform.
Take notes on the variety of terms that describe your research area, as this will help you in both keyword and subject searches.
Lastly, familiarize yourself with boolean operators like AND, OR, and NOT. These operators can help you link necessary information, exclude irrelevant information, and focus your search. Using them effectively can yield more accurate results for your research.
