[Zope] automatically add to ZCatalog?

I have a blog where a search show the latest BlogItems ordered by date I've looked everywhere and can't work out how to automatically add a BlogItemClass instance to my ZCatalog. Currently I have to go to the catalog and click "Find Objects" which is a pain I think I tried to automatically update the whole catalog (3000+ items) but this was too slow to be reasonable. Surely there is a way (in python) to add an item to the ZCatalog and index just it. cheers tom p.s myObj.re_index() doesn't seem to make any difference either -- tom smith http://www.othermedia.com/blog/ 0207 089 5959 3rd Floor, The Pavilion, Newham's Row, London SE1 3UZ
