Cool. (I saw some of your posts on the lucene list). Does this require Saxon 8x? I have done some RAMDirectory searches, but for things like forum posts that need to deny postings that contain 'bad' words (for a young girls portal). But I need to search large collections of XML config and content. The worst thing about this is updating the index, but it is not a showstopper. Can you expand more on: "the underlying > technology is bound to be vastly different wrt. data management, > indexing and transactional properties" it would seem similar to me. That is, if the instance XML changes you have to open the reader, delete the Lucene document, reindex the new document, add it, optimize and close the reader. best, -Rob > > Wolfgang.
