When searching in databases, the following tips will help you refine your results:
Records in library databases are made of "fields." Fields can help narrow your search.

Subject Terms can help you identify effective keywords. Most databases list Subjects in their search results.
For example, in OneSearch:
1. Do an initial search.
2. Under Refine Search click on Subject.
Note: in most, but not all, databases, the AND is implied. For example, Google automatically puts an AND in between search terms.
Example: renewable energy AND China
Example: renewable energy OR solar OR wind
This operator is great when you notice your search term is used in different disciplines. You might use this example when researching peacekeeping in the context of interpersonal conflict but your search results in documents about international conflict.
Example: peacekeeping NOT United Nations
