[Zope] ZCatalog'ing a Web Site

Well, I finally recreated the SiteIndex object + ExternalMethods that reproduces the web page: http://www.zope.org/SiteIndex/newitems.html and it suddenly dawned on me -- such an index is only as up to date as the last time a reindex was done manually, since many of Zope's basic objects are not ZCatalogAware (methods, docs..). So how is the zope.org site managed? Do you run a cron job nightly to reindex the entire site? That'd be quite a load especially on any site with gbytes of objects. Hmm... -Jeff Rush
