When you press the Find button on the data tab, the Find Database dialog will be displayed. You can use this dialog to search for a database by entering part or parts of the database name in the Search Text box at the top. If you search by more than one part of the database name, you need to separate the parts with the semi-colon.
The bottom of the dialog is similar to the Data tab, allowing you to select a database by highlighting it. Only the databases that match your search text will be displayed in the list. When you click OK you will return to the Data Tab with the newly selected database highlighted.
