Disable Server-side search

Hello,

I have a question regarding exchange 2013 activesync policies. 

We have enabled ActiveSyncMailboxPolicy MaxEmailAgeFilter property to oneWeek. It works OK, but the user (who uses Microsoft outlook client for android https://play.google.com/store/apps/details?id=com.microsoft.office.outlook ) still have the possibility to search emails even older than this limit. As I understand this is due to the "server-side search" mechanism. For the security purpose I'd love to disable this feature, so that the user is only able to search those emails, that are downloaded on his device. Is this possible? 

Thanks in advance!
