These are two somewhat different requests. Being able to search on the Received headers would involve a usual kind of term search, but not date searching. This might be problematic as a default because of the volume of received headers. In order to use it for date search, it would need to be parsed for data information and either override the Date:-header or provide a second prefix like received-date. Or maybe a single message could have multiple date: prefixed terms, I'm not sure. d
