[Grok-dev] Re: Installing TextIndexNG3 with Grok

Zope3's full text index *is* supported using hurry.query.query.Text. 
Zcatalog is a zope2 thing.

As of a few months ago,  textindexng-3  did not work with Zope3.  It 
looks like the integration code fell out of step. I'm hoping to have 
some time to spend on it next quarter as I would like to use it on one 
of my projects.
