Databases contains articles with information that will guide you to the answers you seek. Instead of searching with questions on databases, you have to search for information using KEYWORDS.
When extracting KEYWORDS from your assignment or essay, you need to look at the key concepts that encapsulate your assignment.
Is it true that economic growth makes the rich richer and the poor poorer?
Note: The concepts that you are looking for are not always expressed in the
language of the assignment or question, but often through other related terms.
See the Guide for step-by-step instructions.
AND – returns results with both keywords. AND usually limits the search results
OR – returns results with one or the other keyword.It broadens your results by connecting two or more synonyms.
NOT – returns results excluding specific keywords
Use the Boolean Machine for visualizing the effects of Boolean operators .
Quotation Marks “ ” – keep keywords together, for exact phrase searching
Brackets ( ) – keep concepts together, used for synonyms
("green energy" OR "sustainable energy" OR "renewable energy") AND (logistics OR "supply chain")
Building blocks Search strategy

Think of synonyms or alternatives for these words
Write these words under the corresponding keywords in blocks

A URL (Uniform Resource Locator) is a web address for a page or document on the World Wide Web. We can make some educated guesses about the reliability of a web site if we know a little about URLs.
Each URL (for example http://www.whitehouse.gov/about/internships), consists of an access protocol (http), a domain name (www.whitehouse.gov), and an optional path to a file or resource residing on that server (about/internships).
The domain name indicates the organization responsible for the site (www.whitehouse.gov in the example above). The top-level domain indicates the type of site (gov in the example above).
The most common top-level domains and the type of site they indicate are:
In general, .gov and .edu web sites are more reliable than .com web sites.
