Use this option to specify how detailed an index Enterprise Vault is to create by default. The more detailed the index, the more complex the searches that are possible using that index. However, more detail also makes the indexes larger. Therefore, you have to balance the index size against the amount and type of searching that you expect users to do.
. The index that Enterprise Vault creates enables searches on the following attributes of each item: Author, Subject, Recipient, Created Date, Expiry Date, File Extension, Retention Category, and Original Location. If a search matches an attachment to an item, the search result contains both the main item and the attachment.
. As for Brief, and in addition enables searches on the content of each item, excluding phrase searches.
. As for Medium, and in addition enables searches for phrases in the content.

If you change this setting, you must stop and restart the Exchange Mailbox Tasks and the Indexing Services to make the change take effect.
Select this option if you want users to be able to delete items from their archives. This option does not affect the items in mailboxes, only the items that are stored in archives.

. Select this option if you want to be able to recover deleted items from users' archives. If you select this option then, when a user deletes an item from an archive, the item is removed from the archive's index. Therefore, the item can no longer be found by searching. However, direct links to the item such as mailbox shortcuts till work. The deleted item no longer contributes to the archive quota usage.
. If you have selected , this option controls the number of days during which a deleted item can be recovered. At the end of this time the item is deleted permanently.
To recover a deleted item during this time, display the properties of the appropriate archive and, on the tab, click .
This option is used to determine how long to record updates to archives. Updates include adding new items, deleting items and moving items. The update records significantly improve the performance of Vault Cache synchronization by providing records of the changes to an archive since the last Vault Cache synchronization. If a user has not synchronized their Vault Cache within the transaction history period, then Enterprise Vault will process the archive to determine the updates.
Transaction history records are held in the SQL Server, so you need to ensure that the database can accommodate this data.
