You'll likely get a faster response from the Boost user list. See:

Hello Evan,

I'd like to help you, but for that I'd need a little more
info. Could you post some of your source code, like
for instance the instantiation of multi_index_con tainer
you've defined? And what are the specific problems you're
having with ordered indices?

Also, this is probably best moved to the Boost users list,
as comp.lang.c++ is in principle not devoted to particular
libs but the C++ language in general.

Thanks, I didn't realize there was a general boost mailing list. I'll
give it a try. I do note tho that there is relatively low traffic on it,
i.e. < 500 / Mo.

Hmm... Looks like their list server is down. I am unable to register. <sigh>

Well, lets try this example source code:

typedef multi_index::mu lti_index_conta iner<
person,
multi_index::in dexed_by<
multi_index::or dered_unique<
multi_index::ta g<voterid>,
BOOST_MULTI_IND EX_MEMBER(perso n,unsigned long,voterid)>,
multi_index::or dered_non_uniqu e<

multi_index::ta g<lastname>,BOO ST_MULTI_INDEX_ MEMBER(person,s tring,lastname) >,
multi_index::or dered_non_uniqu e<
multi_index::ta g<resstreetnum> ,
BOOST_MULTI_IND EX_MEMBER(perso n,int,resstreet num)> >[color=blue]
> people_set;[/color]

......

int main(){
const people_set::nth _index<2>::type & resstreet_index =ps.get<2>();
pair<people_set ::iterator, people_set::ite rator> range;
range = resstreet_index .equal_range((* domoItor).first );
}

The above code doesn't compile. If you happen to know why, I'd
appreciate some help in getting it going.

Thanks

By changing the pair instance to:

pair<people_set ::nth_index<2>: :type::iterator ,
people_set::nth _index<2>::type ::iterator> range;

I finally got it to compile. I managed this not by reading the tutorial
for the library (the information isn't there) but from reading the
rather prodigious code in multi_index. Yuck!
