Hi:
 Thanks a lot, stefan
  And Brett, Would you like to give your clusterting configuration? Very
appreciate for that.
I got the following error message :
 "*INFO * SearchManager: Node no longer available 1a6ed71e-531
4-414e-95a2-7632c52a7c5c, skipped. (SearchManager.java, line 467) "

Cheers
Perry
