Select the Indexing Service to use for the new vault store. After you have created the vault store, you cannot change to a different Indexing Service.

• Which Indexing Service computer do you want to use to index items in this Vault Store? The list shows computers in the Enterprise Vault Site that have Indexing Services. Click the computer that has the Indexing Service you want to use for this vault store.

• Use Brief, Medium, or Full, to specify how detailed an index Enterprise Vault is to create. This option is not available when you are enabling mailboxes.

  The more detailed the index, the more complex the searches that are possible using that index. However, more detail also makes the indexes larger, so you have to balance the index size against the amount and type of searching that you expect users to do.

  • Brief. The index created by Enterprise Vault enables searches on the following attributes of each item: SharePoint workspace index (Author, Title, Created Date, Modified Date, Folder) and Public folder index (Author, Subject, Recipient, Created Date, Expiry Date, File Extension, Retention Category, Original Location). If a search matches an attachment to an item, the search result contains both the main item and the attachment.

    Medium. As for Brief, and in addition enables searches on the content of each item, excluding phrase searches.

  • Full. As for Medium, and in addition enables searches for phrases in the content.

  The size of the index increases going from Brief to Medium, and from Medium to Full. It is not possible to give an exact size for the index because the size depends on the data that is indexed.

  The different settings probably behave as follows:

  • Brief gives an index that is approximately 3% of the size of the data that is indexed.

  • Medium gives an index that is approximately 8% of the size of the data that is indexed.

  • Full gives an index that is approximately 12% of the size of the data that is indexed.
