Subject Re: avoid overwrite in DataImportHandler
Date Wed, 07 Dec 2011 20:27:50 GMT

I've wondered the same thing myself.  I feel like the "clean" parameter has
something to do with it but it doesn't work as I'd expect either.  Thanks
in advance to anyone who can answer this question.

*clean* : (default 'true'). Tells whether to clean up the index before the
indexing is started.
