This returns an iterator, yep. Please notice that

  es.get<1>()

returns a reference to an index, which is, in many
respects, entirely similar to a regular std::set.
So you have find(), equal_range() etc. just like
in the STL case, with equivalent syntax and semantics.
You might want to give the Boost.MultiIndex tutorial
a further read --anyway, don't hesitate to come back
here if things aren't still clearer.
