now that my collection builds (thanks for the help), i'm facing a
different problem: i want to create joint indexes with mgpp, e.g. a
_single_ index for metadata "title" + "subtitle" (and some others).

i know that this is possible with mg (through comma-separated list),
but i just couldn't manage to do it with mgpp (i'm using gsdl 2.50).

is it possible? and if it is, how?

thanks in advance

jens wille
