如何对复合键控boost多索引容器的一个键执行equal_range，对第二个键执行lower_bound？

#include <boost/multi_index_container.hpp>
#include <boost/multi_index/ordered_index.hpp>
#include <boost/multi_index/member.hpp>
#include <tuple>

struct Data
{
    int key1;
    int key2;
    // other data members
};

typedef boost::multi_index_container<
    Data,
    boost::multi_index::indexed_by<
        boost::multi_index::ordered_unique<
            boost::multi_index::member<Data, int, &Data::key1>
        >,
        boost::multi_index::ordered_non_unique<
            boost::multi_index::member<Data, int, &Data::key2>
        >
    >
> Container;

int main()
{
    Container container;

    // Insert data into the container

    // Perform equal_range on the first key
    auto range = container.get<0>().equal_range(42);
    for (auto it = range.first; it != range.second; ++it)
    {
        // Process the data
    }

    // Perform lower_bound on the second key
    auto lower = container.get<1>().lower_bound(10);
    for (auto it = lower; it != container.get<1>().end(); ++it)
    {
        // Process the data
    }

    return 0;
}
