Hi,
I am having syntax issues and wish to search a bmi container by the
composite index defined below.  I have read about boost::lambdas and
understand how they work.  I simply have gotten stuck in the syntax to
perform the get on the index and how to create the tuple(s) containing the
proper objects.
 
I want to search such that searchKey1="key1" and searchKey2="key2"
and ValidFrom is <= '2013-03-01' and ValidTo >= '2013-02-08'.  Can anyone
help me please?
 
Many Thanks!!
Jeff R.
