You can enter additional criteria for the same field or different fields. When you type expressions in more than one Criteria cell, Microsoft Access combines them using either the And or the Or operator. If the expressions are in different cells in the same row, Microsoft Access uses the And operator, which means only the records that meet the criteria in all the cells will be returned. If the expressions are in different rows of the design grid, Microsoft Access uses the Or operator, which means records that meet criteria in any of the cells will be returned.
