Constantine,
It seems Questel and Elsevier are competitors... But using the same great piece of software !
Best regards, Fabrice

Hi Fabrice,
I used the Xquery delete node command, rather than the (document-oriented) db:delete.
I guess that explains the difference.

Constantine,
Did you mean db :delete or delete nodes ?
I'm using 8.0 769b53b and after db:delete, even without optimize, I get correct documents' count in the GUI window.
Best, Fabrice

Aha, of course, the all boolean. I did not try that, and will.
DB metadata I get via the GUI menu : Database -> Open and Manage
Cheers, C.

Dear Constantine,
From what I know, optimize only rebuilt indexes and metadata.
Did you try "optimize all" to compact db files ?
But documents' number should be updated. How do you get metadata information ?

Hello all,
I've pruned about half the documents of a +-5GB database using XQuery delete. I then optimised the database using db:optimize.
The database metadata still shows the original number of documents, and the overall db filesize remains roughly the same.
I was sort of hoping this pruning would improve performance, but if there's any difference it's negligable. Am I missing something obvious?
Thanks in advance,
Constantine Hondros
