Is there a way to get the entire list of words from the data property of a ZCatalog's TextIndex? I'm trying to obtain the list of words from a TextIndex. In this case, the list of words are very instructive for the client. The idea is to load up a bunch of documents, and then use the ZCatalog to get a list of words in the various documents. We are looking for technical terms (that we don't know a priori). Is there a way to do that? A review of the TextIndex.py source indicates that the TextIndex class has a _data property that contains the list of words. The problem is getting at that property. For example, the following code: S = '' lst = [] if container.abstract_tracker.Indexes: lst = container.abstract_tracker.Indexes.PrincipiaSearchSource.data S = 'Found it' else: S = 'Not there' return S Prompts the following error message...
