I think you might need to read up on hash tables - try wikipedia.
There is no index as such. A dictionary is a hash table
usually implented as a sparce array or tree structure
so you cannot traverse it sequentially - thats why order
is not guaranteed in a dictionary.
I think you need to reconsider your data structure.
