[Koha] Indexing problem

Hello All, I have records in the Koha with biblionumber and biblionumber fields mapped to 090$c and 090$d marc fields. BIBLIONUMBER in : 090$c BIBLIOITEMNUMBER in : 090$d I couldn't index the records as these fields have not been set up properly in the record.abs file. Could anyone provide me the configuration that I have to add on the "record.abs" file to index the records properly? I'd appreciate it. The indexing reports following problem: zebraidx(20053) [warn] Record didn't contain match fields in (bib1,Local-number) Thank you. Best regards, Dibyendra Hyoju
