Nesting refers to the use of parentheses to organize a search statement that uses more than one kind of connector or operator (AND, OR, NOT). Nest search terms whenever there's only one text entry box.
Sample nested search: "critical thinking" AND ("higher education" OR college students)
Same search when multiple text entry boxes are provided:
When you have more than one text entry box, put synonyms or alternative terms for the same concept connected by OR into the same box to be sure that the database combines your terms correctly.
In the examples above, records that contain the exact phrase critical thinking will be identified, and then results will be narrowed to those that also contain the exact phrase higher education or the words college students.
