Database Limits
OvidSP Database Limits focus your search to specific aspects of information. You may apply limits to filter criteria and reduce the number of records in your results set.
Limits are available from Basic Search, Advanced Search, and Multi-Field Search modes. The Limits feature is closed by default, but, once you have logged into your personal account, OvidSP remembers the last state (open or closed) and displays that state when you log in again.
