What if the composite key should be parameterized from a file?
In the case of
<raw>
struct phonebook_entry{
std::string family_name;
std::string given_name;
std::string phone_number;
phonebook_entry(
std::string family_name,
std::string given_name,
std::string phone_number):
family_name(family_name),given_name(given_name),phone_number(phone_number)
{}};
// define a multi_index_container with a composite key on
// (family_name,given_name)typedef multi_index_container<
phonebook_entry,
indexed_by<
//non-unique as some subscribers might have more than one number
ordered_non_unique<
composite_key<
phonebook_entry,
member
phonebook;
</raw>
the lines

Hello,
there's a structure struct person { std::string name; std::string surname; int birth_year; std::string craft; };
How to create such a multiindex container that dumping could performed using an index as name, surname and year triple alltogether? Sounds like you might be interested in MultiIndex's composite key feature:
