[Zope-dev] Different Splitter & Lexicon?!

Hi, Using a latest CVS version of PluginIndexes, I'm finding it practically impossible to use a splitter other than the default ZopeSplitter. Can someone explain to me, like a four year old, how I go about changing the Vocabulary (and anything else I need to do) so that my TextIndexes use a GlobbingLexicon and the ISO 8859 splitter?! cheers, Chris
