[Zope] Convert TextIndex to TextIndexNG

[Lars H. Korte]

Hi,

I would like to use the TextIndexNG Product instead of the normal
TextIndex for SearchableText in portal_catalog.
I deleted the existing SearchableText and added a TING with the name
SearchableText.

Now I think I click on reindex and all my object that were in the old
Index can now be used with the TextIndexNG.
But after reindexing for a while there are no objects in SearchableText.

How can I make my old objects belong to the new index type?

regards
Lars
