Search Structures
Boolean operators are AND, OR, NOT.  Using boolean operators to build your searches will get more precise and relevant results. Use nesting to build search statement. 

Using AND narrows your search by retrieving only documents that have all of your search terms. Use to connect two or three different  concepts.
Example: Internet AND privacy
Example: Women AND sports

Using OR expands your search by retrieving documents that have either of your search terms. Use to connect two or three similar concepts or synonyms or spellings.
Example: Internet OR World Wide Web
Example: University OR College
Example: color OR colour

Using NOT limits your search by returning only your first search term.  It works well when there are multiple meanings of the same word or name.
Example: Saturn NOT car
Example: Java NOT Indonesia

Nesting is used when combing your search terms in one search box.  It is similar to nesting mathematical statements in algebra, so the calculations are done in the proper order.
Example: (hybrid OR electric) AND (Toyota OR Honda)
Example: (university OR college) AND (athletics OR sports)
