It doesn't seem to matter whether fields are stored or not, but I've found a rather striking difference in the memory requirements during sorting. Sorting on a string field representing datetime like '2008-08-12T12:18:26.510' is about twice as memory intense as sorting first by '2008-08-12' and then by '121826'.
Any other tips/guidance like this would be great!
