Anybody know how to properly specify matching rules for importing marc records? I take it that if the rule works, it should show a match in the appropriate column on the "Manage staged MARC records" page before importing. I don't trust my zebra indices, and it appears that the match checks are supposed to match directly between the imports and the database. That's what I want. All I get is "no_match", so I assume I've specified the matching rules incorrectly. What am I doing wrong here?
