Tip # 1
The default connector in Ovid is ADJ (meaning "adjacent"),
rather than the AND default used in many other systems.
If two or more words are entered without a connector between them in
an Ovid database, the system therefore retrieves only
citations in which the words appear next
to one another. Adjacency searching is much more restrictive
than using the AND connector. You may, of course, type

Tip # 3
Begin subject searching by entering only a SINGLE word or
phrase at the Enter Keyword or phrase line and click

not to check that box if you have checked one of the
other listed terms.
Tip # 4
Select the Focus box if you want to limit your search
to articles in which your subject heading is considered the major
Tip # 5
Do not use the browser's "Back" button
when the Continue, Return to Main Search Screen, or Return to Tree Display
button choices are available on the Ovid screens. Otherwise, Ovid may
not be able to maintain the continuity of your session.
