Interested in more websites from the National Institute of Health or the National Library of Medicine?
Narrow your Google search to a specific domain or website by doing a site search:
A. Break your topic down into the main ideas, or keywords. Then combine your keywords into a search query:
Link main ideas together with AND to get fewer search results:
aging AND brain
Link related terms together with OR to get more search results:
healthy OR normal
B. Use quotation marks " " to search words as a phrase:
Searching “healthy aging” excludes articles about healthy eating or rapid aging.
BE AWARE of what your quotation marks are excluding -- searching "healthy aging" excludes articles that talk about aging in a healthy manner.
C. Use an asterisk * to search for multiple word endings:
health* = health OR healthy OR healthier OR healthiest, etc.
