If an Indexes button is displayed on the sub-toolbar, you can browse a list of fields indexed within the database.
From the Basic or Advanced Search Screen, click the Indexes sub-toolbar button. The Indexes Search Screen is displayed.
From the Browse an Index drop-down list, select a field. (For example, Author or Subject—the fields vary by database. You can enter a term in the Browse for text entry field or leave it empty.)
Click Browse. A list of index terms is displayed.
Build a search query by marking the terms and selecting a Boolean operator (and, or, not). Click Search. You are returned to the Keyword Search screen. A Result List is displayed.
