Possible Data Loss

If you delete a document in GlobalSearch, it will be deleted permanently. Your original document files will be deleted, as well as all indexing data. Delete documents with care. Note that deleting a document will not delete the versions of that document for Archives with Versioning enabled.

Select one or more documents from the Search Results Document List.
From the Actions drop-down list, select Delete.
This will permanently delete the document. At the prompt click Delete to confirm the deletion or click Cancel to abandon the delete action and retain the document.
