Add a new field dynamically to each of the result docs and sort on it

[Mark Robinson]

Hi,

My core does not have a field say *fieldnew*.

*Case 1:-*
But in my results I would like to have *fieldnew *also and my results
should be sorted on only this new field.

*Case 2:-*
Just adding one more case further.
Suppose I have other fields also in the sort criteria and *fieldnew *is one
among them, in that case how do I realize this multi field sort also.

Could some one suggest a way pls.

Thanks!
Mark.
