Nope, the entire script is this -

title : field=title
src   : field=src
text  : index

where the input looks like -

src=/home/maky/data/Reuters/newsml/19961130/226516newsML.xml
title=USA: ALPINE SKIING-RESULTS OF MEN'S WORLD CUP GIANT SLALOM.
text= Men's World Cup standings after the giant slalom in  
Breckenridge....

and I use --stemmer=none

cheers,
