X-Query intersect operator

Dear All,
Have anybody used intersect operator before? I have used it but it did not returned any object although there should be.

//price[//@year=2000] intersect //price[//@year=1999]

When I executed those two queries separately I got answer sets which have common elements.

Can anybody help me?

Thanks,
Mustafa.

I’ve tried the same with the cruise schema with Tamino 2.3 and it returns nothing either. Looks like a problem worth raising.


cruise//price[//@yachtid=‘153’] intersect //price[//@file=‘route.gif’]


Separately these return document sets and I can see common ino ids in them, but put together as above nothing is returned.
