-----------------------------------------

Hi Abe-san,

>From what you say, only the single-process example can possibly work with the 
>Lucene output connector that you have proposed.  None of the multi-process or 
>distributed models will work with it properly.

Before you commit to trunk, we really have to think this through, because this 
would be the first connector with such a restriction.  It might be better, for 
instance, to have a secondary process in which Lucene runs, and a socket (maybe 
with a REST API?) where the documents are sent and/or requests are made.  It is 
more work but it is also more consistent with ManifoldCF operating model.

> A output connector for Lucene local index directly, not via remote search 
> engine. It would be nice if we could use Lucene various API to the index 
> directly, even though we could do the same thing to the Solr or Elasticsearch 
> index. I assume we can do something to classification, categorization, and 
> tagging, using e.g lucene-classification package.
