How do I use Boolean search operators?
You can control the number of search results you retrieve by using Boolean operators with your search keywords in LibrarySearch.
This operator reduces the number of results you retrieve because it only finds results containing the keywords specified.
For example: gambling AND addiction
This operator expands the number of results you retrieve because it finds results that contain either or both the keywords specified.
For example: teenagers OR adolescents
This operator excludes results.
For example: psychology NOT evolutionary
|Phrase search " "||
If you put two or more keywords in quotes, you will only retrieve results that contain those keywords in the specific order that you have specified. Make sure to enclose your phrase in straight quotes " " rather than smart or curly quotes “ ” if you are pasting your phrase from a another document.
For example: "climate change"
|Truncation search *||
This operator increases the number of results you retrieve by telling the search engine to search for the root of a keyword and any possible endings.
For example: pollut*
This use of truncation will retrieve results with the following words: pollute, pollutes, pollutant, pollutants, polluting, and pollution.
|Wildcard search ?||
This operator increases the number of results you retrieve by accounting for an additional or alternate letter in a keyword.
For example: wom?n
This use of a wildcard will retrieve results with women and woman.
|Parentheses ( )||
If you are using multiple Boolean operators in your search, you can use parentheses to stipulate the order that you want them to be executed in by the search engine.
For example: ("artificial intelligence" OR "AI") AND labo?r NOT ("human resources" OR "HR")
