What's most important to remember with keyword searching--

Long phrases will NOT work in the Library Catalog and most subscription databases.

For example, let's say your search topic is "The influences of food advertising on children."  That's a fine topic but plugging that into a database will most often give you no results.  So here's the Library's main advice.  Break your search topic into search terms of your phrase and place AND in between each of them.    The Connector, AND, will most often appear BETWEEN your search terms.  In the database example below, AND is the CONNECTOR chosen for the second and third line.
