[Koha] Record matching rules setup for the 024

Hello, I've been trying to set up record matching rules for the 024 using the following : Match point 1 1. Search index: Identifier-other 2. Score: 1000 Matchpoint components 1. Tag: 024 2. Subfields: a 3. Offset: 0 4. Length: 0 5. Normalization rule: Identifier-other However, it does not work. Records I am importing do not find matches and I know that some of the records in the small batch of records I am trying to import do have the same 024s. We are on Koha 3.16.03 _________________________ Cecil Hillyard Technical Services-- Cataloger Washoe County Library Reno, NV 89501 https://library.washoecounty.us<https://library.washoecounty.us/>
