Exalead:Desktop search mail with Authors and Attachments keyword

There are two key things that are missing from the Exalead:Desktop. Specifying in the query Authors and Attachments. The data for both are already there so I think that are easy to add.

I would think everyone would love to be able to search for:

/foo|bar/ source:"outlook" Authors:Dave* hasAttachment:true

Maybe it's already there but for the life of me I can't find it.
