hi zopistas

how do I use ZCatalog's DateRangeIndex, any example/documentation to point me?

A DateRangeIndex is to be used when you have objects which, for example, have a publication start date (date_first_pub) and a publication end date (date_last_pub). To find objects which are published today, you then just have to : - create a DateRangeIndex, called for example 'pub_date', with fields 'date_first_pub' and 'date_last_pub' - query your catalog, with "catalog({'pub_date': DateTime.DateTime(),...})"

And that's all !!
