Using MOSS 2007. The only OOtB options for sorting search center results are Relevance and Modified Date. There doesn't seem to be a way to do it through the XSL. I was wondering if and how I could extend this (sort by Created for example, and it doesn't have to be a selectable option...it can be ONLY that). I assume this needs to be done programmatically which I'm comfortable with. I'm not asking for the code for how to do it (though it's welcome!) but more of an explanation on how to go about it, if possible. What classes to use, etc. to make the behavior the same as if it were built into the search center.
I've been googling for hours and I can't find what I need. Thanks for any help you can offer.
