C++ which container "a la map" to store different objet

I have to type of very complex object A and B in 2 vectors:
```
vector<A> va;
vector<B> vb
```
I want to loop over va and vb, and store pairs in a C++ container:
```
for(i:va)
  for(j:vb)
    container[i]=[j]
```
notice that the container can have several time the same "key" object.
I wanted to use a multimap but A and B are very complex compound data type and I do not want to slim information when setting the "key".
My final goal is to be able to access information for i and its corresponding j in the container.
Do you know which container is suitable for this task?

You *could* store pairs of iterators in the multimap.. Assuming the vectors aren't updated after some point in time, and the iterators aren't invalidated. – StoryTeller - Unslander Monica Sep 06 '16 at 16:48
It is not clear what 'slim information when setting the "key"' means. Could you rephrase that? – Beta Sep 06 '16 at 16:51
What about a multimap containing pointers to elements in `va` and `vb`? – Tristan Brindle Sep 06 '16 at 16:51
StoryTeller: your solution seem complicate – cabe Sep 06 '16 at 16:55
Beta: I mean that I want to be able to keep all the information of the object. – cabe Sep 06 '16 at 16:55
Tristan: your idea is quite interesting. I'll try this and see. – cabe Sep 06 '16 at 16:56
Thank you all for your help. – cabe Sep 06 '16 at 16:56
