Subject Re: PipeLine for Solr
Date Mon, 18 Apr 2011 16:56:14 GMT

We've been thinking about the same for some time, and I put together a WIKI page discussing
the need for such a pipeline. Feel free to edit, extend and discuss inside the WIKI.

It need not be a part of Solr as such, but it is crucial that there is one preferred pipeline
where the community can gather their effort in writing re-usable processing stages.
