Search results of Vault Cache in Outlook returns significantly fewer returns than a WDS search
We have a case number - 415-611-058, regarding to the following issue:
When attempting to perform a search within outlook client (Instant search) for items that are stored in the Vault Cache, the results are not accurate,
In compression to the same search in WDS outside the Outlook client or same search in Archive explorer. Items that could be found in Archive explorer \ WDS are could not be found when searching in instant search.
Please notice TSE explanation as follows:
When performing the same search in Instant Search and Windows Desktop Search (WDS) less results appear on Instant Search. It is even possible that Instant Search doesn't show any results while WDS does.
Instant Search is searching for items in the Vault Cache when searching Virtual Vault. Vault Cache is made up of two parts, The MetaData Cache
and the Content Cache.
The MetaData Cache is an MDC File (which is in a PST Format) that contains metadata for all the emails in Vault Cache and folder structure.
The Content Cache are dozens of DB Files (also in a PST Format) separated in to date ranges and have the full messages including attachments.
When you open up Virtual Vault you see the structure and messages held in the MDC, when you click an item to preview it you will see the
preview as held in the MDC file, when you open up the message, it is then retrieved from the DB file and displayed as a message within
When you search through Windows Search, you search both the Metadata and Content Cache, you can search all message content.
In Outlook, under the Instant Search Options you will have to select the data files to search, in this case you should be presented with any
PST's currently attached within outlook and the Virtual Vault itself, which is the MDC only. In File->Data Management it can be seen that only
the .mdc file is included. So when searching for words that aren't present in the message as previewed, for example some words on the message
body that don't appear when previewing it, no results are returned.

You will need to register to gain access to the resource but this is very easy.
Once you are logged in click on the Create Content menu and then the Idea link, which is where you can provide the details of your request.
As per our agreement I will not archive the case immediately, I will leave it open until end of business on Wednesday and if I have not heard anything from you to indicate the case cannot be closed I will go ahead and archive it.
According to this explanation, Searching inside outlook (Instant search) for vault items, won't be effective, it will only work when searching words that located within the preview part (120 first words) of the message body.
