boost::MultiIndex help

I'm using boost multi index for the first time. I've managed to populate
the container with my data & now I am trying to get the non-unique
ordered index to work. Does anyone have a source example (not from the
boost.multiindex tutorial please) used to get a list, set, whatever, of
tuples from such a search on such an index?

Thanks,
Evan Carew

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_container
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::multi_index_container<
person,
multi_index::indexed_by<
multi_index::ordered_unique<
multi_index::tag<voterid>,
BOOST_MULTI_INDEX_MEMBER(person,unsigned long,voterid)>,
multi_index::ordered_non_unique<

multi_index::tag<lastname>,BOOST_MULTI_INDEX_MEMBE R(person,string,lastname)>,
multi_index::ordered_non_unique<
multi_index::tag<resstreetnum>,
BOOST_MULTI_INDEX_MEMBER(person,int,resstreetnum)> >

people_set;

......

int main(){
const people_set::nth_index<2>::type& resstreet_index=ps.get<2>();
pair<people_set::iterator, people_set::iterator> 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
Evan Carew

range = resstreet_index.equal_range((*domoItor).first);
}

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!
