Use the "Restrict by date" option to limit the your search to documents that were published during a specific time period or single date.

The default restriction is for the "Previous 2 years," which means the system will only return those items satisfying your search criteria that have been published or made available to the general public in the two years up to today's date.

To change the date restriction for your search, select an option from the "Restrict by date" drop-down list. Depending on your selection, the system will display one or more customizable fields for configuring your restriction.
