Big problem: search in mail AND its attachments

Hi, comparing the 8.2 version with windows search I discovered that X1 searches separately emails and their attachments.
That means that if I have an email with a text "Customer" that has an attachment (might be also an email) with text "Apple" and I search for

Code:

Customer AND Apple

I find nothing, neither in the "All" view since X1 does not find an item that has both terms! Windows search finds it (correctly) since the attachment is part of the mail.
Is it a big open problem or should I search differently?
thanks

Giuse
