Searching between search lines is an implied AND. Within a search field, use the search operators: OR, NOT, and AND
Examples, searching the “Title” field for:
Italy OR Rome
All titles containing either the word Italy or the word Rome
Italy NOT Rome
All titles containing the word Italy, but not the word Rome
Italy AND Rome
All titles containing both the word Italy and the word Rome
Italy AND “in Rome”
All titles containing the word Italy and the phrase “in Rome”
Italy AND (Venice OR Florence)
All titles containing the word Italy and also either the word Venice or Florence
(Italy AND Venice) OR Florence
All titles containing either Florence or both Italy and Venice
One powerful way to use boolean search is in searching the “Subject” field. For example you can use it to exclude certain Subjects.
Subject is: music AND school
Subject is: (music AND schools) NOT “juvenile fiction”
The second search line above will exclude all juvenile fiction.
You must use regular quotation marks – smart/special quotation marks are ignored.
To use multiple search operators, use parentheses to designate order.
Unlike with proximity search, you can use quotes with boolean search.
