Thank you for your answer, this "qstring" works very well (my map was
already in the FOOTER section of the query-template):
http://sit.comune.lugo.ra.it/cgi-bin/mapserv?mode=itemnquery&mapxy=17294
87.0255+4927174.2505&scale=2000&map=/dati/sit/Lugo_base.map&mapsize=&lay
er=CTR_5000&layer=Mappali&layer=Quadrocatasto&layer=Grafo_stradale&qlaye
r=Mappali&qitem=PARTKEY&qstring=/E730%20%20%2077%20%20427|E730%20%20%207
7%20%20428|E730%20%20%2077%20%20266/

But I have to specfiy "mapxy" and "scale" (as if I had "clicked" on the
map) to have querymap centered on my features; if I omit "mapxy" and
"scale" I obtain query centered on the entire extent:
http://sit.comune.lugo.ra.it/cgi-bin/mapserv?mode=itemnquery&map=/dati/s
it/Lugo_base.map&mapsize=&layer=CTR_5000&layer=Mappali&layer=Quadrocatas
to&layer=Grafo_stradale&qlayer=Mappali&qitem=PARTKEY&qstring=/E730%20%20
%2077%20%20427|E730%20%20%2077%20%20428|E730%20%20%2077%20%20266/

How can I center (and scale) my querymap without previously calculate a
mapxy point near the queried features?

Thanks,
  Daniele
