[Boost-users] How to sort multi_index_container + composite_key + Sort by Vale. Is it possible?

Is it possible to sort the container by value? In below example by "member" Or also other keys like: Sort by "member" typedef multi_index_container< Element_Entry, indexed_by< ordered_non_unique< composite_key< Element_Entry, member, member, member, member > >, ordered_unique< member > >

ElementRecord;
