Searching Databases: Using "Connectors"
AND / OR / NOT
AND - Searches for articles containing both terms. Use to combine main concepts or variables in your search.
Example: sleep AND health = results containing BOTH the words "sleep" and "health."
OR - Searches for articles that contain EITHER or BOTH terms. Use for synonyms or related terms.
Example: women OR woman OR female OR girl = all results that mention women regardless of which term an author uses
NOT - Searches for articles that do NOT contain a term. Use sparingly.
Example: education NOT technology = results using the term "education" but not the term "technology"
Remember: Use each search box in a database to represent a "main concept" in your search.
Here's an example a search for information about the relationship between sleep and anxiety or depression in women.
![Separate synonyms for a main concept with "OR." Leave the drop downs between search boxes on "AND"](//s3.amazonaws.com/libapps/accounts/71117/images/PsycINFO_Search.png)
