First of all: do you need key-value container (map/hash map)
or just sequential one (list/vector)?

If you need it to be both at the same time, multi-index is the way to
go then and you
need need 2 indices, ordered and sequenced, for example:

typedef multi_index_container<
  std::string,
  indexed_by<
    sequenced<>,
    ordered_unique<identity<std::string> >
  >
> text_container;
