[Boost-users] Update the index of a hashed_non_unique entry in boost::multiindex

I have a boost::multiindex container which has an index as follows :

boost::multi_index::hashed_non_unique<

            boost::multi_index::tag<IndexByNonUniqueId>,

            boost::multi_index::const_mem_fun<StoredObj, std::string,
&StoredObj::getNonUniqueIdString>

        >

This ID comes in as ""(empty string) when I initially get the object. I add
it to the multiindex at this point. But later in the course of the program
the ID gets populated using its "setNonUniqueId" method. At this point of
time inside "setNonUniqueId" I would like to update the index to the
object(in the multiindex) as well(while the ID is being updated from "" to
something concrete). How do I do this? How do I locate the specific object
and update the index?
