Hi Ramesh,
Just use the iterators provided by the second or third index. For
instance (not compiled, beware typos):
for (MyMap::index_iterator<Key2>::type it =
MyContainer.get<Key2>().begin(),
itend = MyContainer.get<Key2>().end();
it != itend;++it) {
cout << it->Key1;
cout << it->Key2;
cout << it->Key3;
}
