sort search result with different property for different page type.

Hi,

Could some help me?

I have a below requirement from client

PageType Article

{

DateTime Created;

DateTieme Update;

}

PageType Product

{

DateTime Created;

DateTieme Update;

}

We have requirement to sort the search result in following way.

when sorting is by latest, it would sort by page's updated date,

Except: Product pages, those should show in created date order.

Thanks,

Mahesh Kulkarni
