I am looking for a bidirectional container.
Requirement Detail:
I need to build a data base where by giving the key i should be getting the list of values. And vice versa [i.e By giving One Value get the list of keys]
 
Eg:

For Getting the stacks [SHOULD be in same sequence]
Given an element id -11 stacks should be 5, 7 & 4 [Same sequence]
For eid id 16 – stacks ids - 5, 2 & 7
 
And for the other way...
Given the stack id 5 eids should be - 11, 16, 7 & 12 [Not necessary to be in same sequence]
For stack id 4 – eids- 11 & 12
 
Please let me know if i could achieve this requirement by using one boost container
 
Any help in this regard would be highly appriocated
