If you use boost on the date field the way you suggest, remember
you'll
have to reindex from scratch every year to adjust the boost as items
age.
Or maybe just use a method such that 2007 dates boost the document
by 3.0,
2008 dates by 3.1, 2009 by 3.2 ... Whether this is feasible
depends on how
else you are expecting other scoring boosts to interact with document
intrinsic boosts.
Don't do date boosting at index time, but rather tune things on the
query end, using FunctionQuery and such. That'll give you maximum
flexibility.
