Otis, thanks for the answer.
Unfortunatelly the index *directory* remains larger *after" the optimization. In our case the otimization was/is completed successfully and, as you say, there is only one segment in the directory. Some other ideas? Thanks, Yuliya > -----Ursprüngliche Nachricht----- > Von: Otis Gospodnetic [mailto:otis_gospodne...@yahoo.com] > Gesendet: Donnerstag, 7.
