I want to get the news items by date. for eg...news items created on a particular date.

I tried with container.portal_catalog(created='2003-08-13'), container.portal_catalog(created='2003/08/13') and many other....

But i am not getting anything in result...though i have some data...

Is there any problem with date format...??? if yes please specify me the correct format??

I think that you have to pass a DateTime object and not a string: from DateTime import DateTime container.portal_catalog(created=DateTime('2003/08/13'))

Also remember that it is very unlikely that a document is created at 'some_date 00:00:00' (this is what you effectively get from "DateTime(some_date)"). You will need a range query to effectively search for dates. Please read the appropriate section in the Zope Book (2.6 edition). Dieter
