When a user "deletes" a document, the document is removed from the current folder or view. In databases which have folders designed to show hidden documents, the documents will now display there. In mail databases the documents will be placed in a hidden folder, ($SoftDeletions), which is part of the mail template. The document is then deleted permanently from the database depending on the value set in the "$Undelete ExpireTime (in hours)" setting on the Advanced tab of the Database Properties box. The default for this setting is 48 hours. It is the Update Task which actually performs the deletion of the document.
For Domino versions prior to Domino 5.0.12 the number of soft deleted documents is limited to 1000, after which extra documents will be hard deleted. Starting in Domino 5.0.12 and Domino 6.0, the Maximum number of Soft Deletions is 32,768.

Internally in Notes/Domino, the soft delete duration value is stored in two different places. One of the places the soft delete duration value is stored is in the Icon note of the database. The Icon note is what replicates around to other servers. This is also where the value that displays in the Database Properties dialog box is extracted from when looking at the Database Properties.
The other place that the soft delete duration value is stored is the SoftDeleteRetainDuration field in the database header. This field is what the software actually uses when determining how long to hold documents in the Trash folder.
Немного о дизайне
Есть папка Trash и view ($SoftDeletions). При этом интересно, что взгляд не имеет View Selection (а для чего он нужен-то, если при его создании надо выбрать тип (фактически, условие выборки) "Shared, Contains Deleted Documents"?) и, если открыть его в дизайнере, то на табуляторе будет указано Trash - View.
Trash в клиенте имеет функциональность папки, так как в него можно перетащить.
И еще, что интересно его называют Anti-Folder View
