[Zope] Zope-Product SiteSearch?

Hi I just tried the ZOD product (Zope Online Documentation) but was not successful because there seems to be a dependency to an other Zope product that I failed to find on www.zope.org The error message I get is: 2002-10-02T20:57:34 PROBLEM(100) ZODB Could not import class 'SiteSearch' from module 'Products.Site Search.SiteSearch' Any tip where to find this product is welcome. There are two HowTos related to the search term 'SiteSearch' but unfortunately nothing that looks like a product. Peter
