Nesting
Nesting is a way of grouping similar concepts together. It also lets you control how the terms are searched.
Words are nested together by using parentheses ( ) in your search.
Search Example:
(elderly or aged) and (fall* or tripping)
The database will search for what is contained in the parentheses ( ) first, and will then combine the two. For example the database will look for elderly or aged and then look for fall* or tripping, and finally will combine the results.
Nesting allows you to use two or more boolean operators (AND, OR, NOT) effectively within the one search strategy.
