Boolean operators work in all databases. You either enter manually or the database supplies them for you Use AND, OR and NOT to combine terms to be searched over one or more fields.
Here’s an example of a search statement created using Boolean operators:
(cars or automobiles) and manufacturing and computers not trucks
Using the NMC Journal List:
When you want to get at all the possible variations of a word in a database, you need to use a technique called truncation. Truncation means to cut off or shorten. By cutting a word to its base and adding a truncation symbol, you tell the database to find the word in all its variations. Use truncation when you want to be as comprehensive as possible in your search. Different databases use different symbols.
Truncate your search term in most databases by putting * (asterisk) at the end of a root word.
Ex. ENVIRONMENT*= ENVIRONMENT or ENVIRONMENTS or ENVIRONMENTAL or ENVIRONMENTALISM
iLink the Library Catalog:
Truncate your search term by putting a $ at the end of a root word.
Ex. SPEAK$ = SPEAK or SPEAKS or SPEAKER or SPEAKERS or SPEAKING.
Quotation marks work in most databases. Databases do not recognize common phrases. If you search with a phrase, like art therapy, put quotation marks around it.
Quotation marks force the database to search for the phrase as a whole, not just the words here and there. The databases search for exactly what is in quotation marks, so be sure to check your spelling.
Ex. "art therapy" "asian carp" "type 2 diabetes"
