Boolean Operators link concepts and are used to broaden or narrow your search. Briefly, here's how they work:
AND - finds results with your all search terms. AND narrows your search so that you retrieve fewer articles.
OR - finds results with any of your search terms. OR broadens your search so that you retrieve more articles.
NOT - finds results without the specified search terms. NOT narrows your search but it can be tricky to use.
By default, ASFA assumes an AND relationship between your search terms.
Take a look at the Boolean Operators guide for more detailed information about how to use this valuable search technique.

Sometimes you will want to search for a specific phrase rather than searching for individual, single words and combining them with the Boolean Operator AND.
When you do a phrase search, the record will have to contain all of the words, in the order you specify, and right next to each other.
To specify a phrase search, simply enclose the phrase in quotation marks. For example:
Doing a phrase search results in fewer, generally more relevant, results. These are examples from ASFA:
sustainable fisheries retrieves 29,806 records
"sustainable fisheries" retrieves 1,274 records
Phrases and single words can be searched in combination, and will be linked with AND, as in this example.
"sustainable fisheries" tuna "longline fishing"
