# 使用筛选器导航

要使用逻辑 OR 连接多个筛选条件，请点击筛选器栏上的「筛选器导航」图标。将显示「筛选器导航」窗口。

The filter conditions that have been set appear in the Filter navigator. As soon as a filter is set, you see a blank filter entry at the bottom of the Filter navigator . You can select this entry by clicking the word "Or". Once you have selected the blank filter entry, you can enter additional filter conditions in the form. These conditions are linked by Boolean OR to the previously defined conditions.

The context menu can be called for each entry in the Filter navigator. You can edit the filter conditions in this area directly as text. If you wish to check if a field has content or no content, you can select the filter conditions "empty" (SQL:"Is Null") or "not empty" (SQL: "Is not Null"). It is also possible to delete the entry by using the context menu.

在「筛选助手」中，通过拖放，或使用 命令 Ctrl+Alt+向上方向键或 命令 Ctrl+Alt+向下方向键，您可以移动筛选条件。要复制筛选条件，请在拖动时按住 命令 Ctrl 键。

While designing your form, you can set the "Filter proposal" property for each text box in the Data tab of the corresponding Properties dialog. In subsequent searches in the filter mode, you can select from all information contained in these fields. The field content can then be selected using the AutoComplete function. Note, however, that this function requires a greater amount of memory space and time, especially when used in large databases and should therefore be used sparingly.
