As far as I know you can't build records in PythonScripts which are 
needed to add the new kind of Indexes... Maybe some interface should be 
implemented into the Zope-Core to do this kind of stuff.

In the meanwhile you can try something like this in an External Python 
Method:


         class Extra:
             """ Just a dummy to build records for the Lexicon.
             """
             pass

         wordSplitter = Extra()
         wordSplitter.group = 'Word Splitter'
         wordSplitter.name = 'Whitespace splitter'

         caseNormalizer = Extra()
         caseNormalizer.group = 'Case Normalizer'
         caseNormalizer.name = 'Case Normalizer'

         self.Catalog.manage_addProduct['ZCTextIndex'].manage_addLexicon(
                                                     'Lexicon', 'Lexicon',
                                                     (wordSplitter,
                                                      caseNormalizer))

         extra = Extra()
         extra.index_type = 'Okapi BM25 Rank'
         extra.lexicon_id = 'Lexicon'

         self.Catalog.manage_addIndex('mDate', 'DateIndex')
         self.Catalog.addIndex('mSubject', 'ZCTextIndex', extra)
