Hibernate version:1.2 at the moment

My problem
Hi guys,
sorry I ask here in the forum but i didn't found anything in the documentation and with google.

I hope anyone have a good idea for my problem.
I have a DB with up to 10000 objects.

I search in my program after these objects with different criteria with : session.Find


I save the objects I loaded locally, as example I load 5000 objects, and now I want search after more objects with NHibernate, and NHibernate find now 1000 new objects an 2000 already loaded objects.

My Question: Is it possible to say NHibernate he hadn't to load already loaded objects?

sorry for my terrible English.

Greetings

You're probably looking for the second level cache:
