What are Boolean operators?
Answer
Boolean Operators are simple words (AND, OR, NOT or AND NOT) used as conjunctions to combine or exclude keywords in a search, resulting in more focused and productive results.
Combine your keywords and use boolean operators to get the best results. You can also choose for your keyword to be only in the journal/title, abstract, or in the whole text of the record.
In Primo and other systems the operators are usually active in the advanced search.
And |
searches all of the terms entered in the query. Ex. (air AND pollution). If one term is contained in the document and the other is not, the item is not included in the resulting list Use it to narrow your search. |
Or |
results contain either the one or the other term or both. Put your search terms in the bracket and the OR operator in the middle, Ex. (Canada OR USA). Use it to broaden your search. |
Not |
searches only the first term that do not contain the term if you want to search for the animal and not your star sign! ex. (Capricorn NOT astrology) Use it to narrow your search. |
Combine the searches to get the best results for your topic.
