I worked on tweaking Nora&#39;s rule to work for me on my system (running DB rev 3.01.00.144, just a few behind HEAD), and got the following as a working, stand-alone rule:<div><br></div><div>Match threshold: 100</div><div>
<br></div><div>Matchpoints (just the one):</div><div><br></div><div>Search index: Control-number</div><div>Score: 101</div><div>Tag: 001</div><div>Subfields: a</div><div>Offset: 0</div><div>Length: 0</div><div>Normalization rule: Control-number</div>
<div><br></div><div>Required Match checks: none (remove the blank one)</div><div><br></div><div><br></div><div>I&#39;d love to see further documentation on how to choose the search indexes and normalization rules... or perhaps a dropdown of implemented options.</div>
