you can do this by using the fielded searching provided by MGPP (an alternative
indexing program). to use it you need to edit the collection config file
(collect.cfg). Have a look at http://www.greenstone.org/manuals/mgpp_user.pdf -
the mgpp user guide.
and yes, you need to rebuild the entire indexes whenever anything new is added.
