In some cases, you might want to filter the underlying workspace by limiting the number of items in a given field or fields. By using the Column Filter Bar, and entering the filter text appropriately, you can reduce the number of records displayed. When the Column Filter Bar is activated, a blank row with a grey separator line appears directly above the uppermost data row in the grid (as shown in Figure 1).
It can be activated by clicking on the Column Filter Bar button on the toolbar or from the following menu: View » Column Filter Bar. To activate a filter, enter the filter text in the box immediately below the corresponding column and click the Execute Filter Bar button on the toolbar (or press the Enter key). For Boolean fields, enter 1 for true and 0 for false.
