We use boolean operators locate articles with our search terms.
The two basic boolean operators are: AND and OR
Use them to either narrow or broaden your results.
AND narrows the results: ALL search terms connected with AND must be present in the article records returned.
OR Broadens the results: ANY search terms connected with OR can be present in the article records returned.
Broaden a search by using the truncation. The truncation symbol is an asterisk (*) put it at the end of the root of the word. Example, immigra* retrieves immigration, immigrant, immigrants, immigrate, immigrates.
If your search term has more than one word, and those word must stay in that order to make sense, use quotation marks around your search term for exact phrase searching. Example: ”Global warming"
Most databases offer facets to limit your results further (typically on the left)
