Looking for someone's help me to make correct use of boost composite key.
Requirement:
Given config and type get all cid's
Below example I am passing config =1; and type = 1; I am expecting all cid's matching both of them. i.e 1 and 2 only
However if you see the out output it is: 1,2,3,1,8,3

#include <boost/multi_index/ordered_index.hpp>
#include <boost/multi_index/member.hpp>
#include <boost/multi_index/composite_key.hpp>
#include <iostream>
#include <vector>

struct record
{
    unsigned int cid;
    unsigned int config;
        unsigned int type;
    //! default const..
    record():cid(0),config(0),type(0){}
    //! parm. const..
    record(unsigned int _cid, unsigned int _config, unsigned int _type): 
        cid(_cid),config(_config),type(_type){}
};

using boost::multi_index_container;
using namespace boost::multi_index;
typedef multi_index_container<
    record,
    indexed_by<
    ordered_non_unique<

    member<record,unsigned int,&record::config>,
    member<record,unsigned int,&record::type>

recordBookDef recordbook; 

int main() 
{
        record obj1(1,1,1);
        record obj2(2,2,1);
        record obj3(3,3,1);
        recordbook.insert(obj1);
        recordbook.insert(obj2);
        recordbook.insert(obj3);

        record obj11(2,1,1);
        record obj12(1,2,1);
        record obj13(8,2,1);
        recordbook.insert(obj11);
        recordbook.insert(obj12);
        recordbook.insert(obj13);

        unsigned int config =1;
        unsigned int type = 1;
   recordBookDef::iterator it=recordbook.find(boost::make_tuple(config,type));
    while(it!=recordbook.end())
    {
                //if(it->config == 1)
                        std::cout<<it->config<<",";
        ++it;
    }
        std::cout<<std::endl;
  return 0;
}
