Advanced Google Searching: Google Search

Combine Boolean and Domain Searching

You can see more details on Boolean and Domain Searching below this box. The following two examples provide you specific contexts where you may want to employ both tools.

To find information on the credibility of Wikipedia and exclude results from Wikipedia: wikipedia credibility

To search multiple sports sites for information on concussions and include alternate terms (note the quotation marks which allow you to limit your search to a specific phrase)

( OR OR concussion OR "head injury" - provides most results and includes many news stories on players with concussions

( OR OR "concussion research" OR "head injury research" - results focus on research (e.g., money awarded, universities conducting research, etc.)

( OR OR "concussion" OR "head injury" opinion - results focus on opinions (players, journalists, etc.) on concussions (e.g., impact of, lawsuits related to)

Domain Searching

Domain searching allows you to limit your search to a specific domain (e.g., .edu or .gov) or to a specific site (e.g.,  This can be useful when your instructor asks you to use only credible sources (hint: limit to .edu and .gov) or you're wanting to leverage Google's searching algorithm to search your favorite site. 

You can use this link which will pre-populate a Google search box with the correct syntax (just change the capitalized text to fit your criteria) or you can use Google's Advanced Search page

Boolean Searching

Google allows you use Boolean searching, or in non-librarian terms, use AND, OR, and NOT to customize your search results.With Google, you must capitalize the words (otherwise, it will treat them as search terms).

See below for more information on how to use them.

Example:    football AND concussions

This search will return resources relating to both football and concussions

Example:   "heart attack" OR "myocardial infarction" 

This search will return resources that include either the popular or the medical term

Example: Consussions NOT football

This search will return resources that include concussions but not mention football

Example:("College Students" AND Concussions) NOT (sports OR football)

In this example, we include college students in quotations to include only articles with this specific term. Then, we use AND to limit articles to only those discussing both college students and concussions. We, then, are only interested in articles that are unrelated to sports concussions. So, we can use the NOT to exclude those. I included football, as well, as some articles may mention a specific sport, and football, recently, is the most discussed sport. The parentheses are useful to ensure OneSearch interprets your query correctly.
