Google Search Tips!

To search for multiple concepts: 
- use ORs between words for the same concept,
- use quotes (" ") around phrases.
-  Google does not use the *

To limit to a specific domain, use site: in front of the domain name (no spaces)   will limit a search to just .edu sites OR   
will limit a search to either .edu or .gov sites  
will exclude .com

Database Searching


OneSearch feature located on the Library's home page will save you time as it searches across most of our article databases and book catalog to find sources matching your search terms with one click.  Sources include a wide range of articles from academic journals, popular magazines, newspapers and reference sources, e-books & other documents, plus print books available in the library. 

Preparation Needed BEFORE you search:  Use the key terms discussed above to write out your search string of key concepts.

Search tips to help you narrow or broaden your search results: 

  • Type an OR between synonymous words for the same concept.
  • Use AND between concepts to narrow and focus your research 
  • Use an * to search for multiple words from the same root, e.g. legislat* will find articles with the words: legislate, legislation, legislator or legislated
  • Use quote marks (“ ”) around search phrases (multiple words that should be searched together), e.g. “racial discrimination”

Here are some examples: 

 (your city) AND biome AND "life forms" OR organisms AND "endangered species"


(your city) AND biome AND "life forms"

(your city) AND "life forms" OR "organisms" AND "endangered species"
