The support for SWISH is in the development engine, and is development
code ...

Well, at the moment the version of SWISH thats included in the development
code base is seriously hacked, mainly to allow it to sensibly recognise and
index SOIF files. I have been meaning to contribute these changes back to
the SWISH development effort, but as yet they're not really stable enough
to do so. As you mention, SWISH performance with large document sets is
fairly poor (although some changes can be made to improve it) - I've
yet to investigate SWISH-E, although it does look like it may be a good

any file format other than SOIF. The Harvest gatherer robot handles all of
the necessary file format conversion.
