Clearing a Forest
You can clear the document data from a forest using the Admin Interface. Clearing a forest removes all fragments from the forest, but does not remove its configuration information.
To clear all data from a forest, follow these steps:
Click Forests in the left tree menu. A list of forests appears.
Click your target forest.
Click the Clear button on the Configure tab.
A confirmation message displays.
Confirm that you want to clear the document data from this forest and click OK.
Clearing data in a forest is a “hot” admin task; the changes take effect immediately.
