All, Is it possible create a multi_index_container with keys in non sequenced order? i.e, in the below example while extracting the element book entry can I send the node1 and node2 in different order than how it is created? elementbook pb; Elem_entry fc1 = Elem_entry(1,90,99); Extracting: elementbook::iterator it; it = pb.find(boost::make_tuple(99,90)); ????? Is it possible to simulate this requirement? typedef multi_index_container< Elem_entry, indexed_by< //non-unique as some might have more than ids ordered_unique< composite_key< Elem_entry, member<Elem_entry,unsigned int,&Elem_entry::node1>, member<Elem_entry,unsigned int,&Elem_entry::node2> > >, ordered_unique< member<Elem_entry,unsigned int,&Elem_entry::faceid> > >
elementbook;
