I am sorting against an epoch time stored in my index. By using:
contactDocument.add( Field.Keyword( "epoch_time", epoch );
Then I sort by this field. My search time is in the order of 3sec on an
index of about 6G using simple searches against a text field. By using
boosts I was hoping to increase performance. Do you think this will make a
big difference?

I've been effectively off-line for a few days, so I'm not sure if
anyone has replied on this thread yet.
Using boosts will definitely use less resources than sorting. If you
do use sorting for dates, be sure you're doing it numerically rather
than lexicographically.
