Yes, but best if you use the grs.marcxml input record type,which 
represents the record *internally* in a MARCXML-based structure. This 
will work with the marc21.abs indexing rules in the Zebra distro, but 
not the older, clunky usmarc.abs rules.

This sounds like something is going wrong. When you've loaded MARCXML, 
it should be trivial to get back MARC.

Have you tried using the YAZ client to get records out? What do they 
look like?

Mike? Is there some trickery to how you use sort from ZOOM?

Zebra has a shortcut that allows you to attach sort criteria directly to 
the query. From the CHANGELOG:

When I use Zebra as the dedicated search engine in an application I 
usually use this technique to save the extra PDU exchange.. you simply 
add sort directive on the query by ORing terms on as above.. for instance:

f @or water @attr 1=4 @attr 7=1 0

Produces a result set holding the records matching 'water', sorted in 
increasing order by title.

This is a feature I have been missing myself for years.. at the moment, 
to my knowledge, there is no way to do this...
