Helo Michael and Katrin, I started at KOHA server z39.50. And from this server (own) I download the record by the protocol z39.50. I noticed when the record is related to the authority which form old term - "see from" (in downloaded record via z39.50) contains data from "old term" with the first indicator = z. Authority record: =LDR 00804cz a2200217n 4500 =001 1087296 =003 LIB =005 20160910184902.0 =008 970731n||a|\nnaabn\\\\\\\\\\|a\aaa\\\\|c =010 \\$an 97081941 =040 \\$aLIB =100 0\$aAntonio Rosmini Serbatid(1797-1855). =400 1\$aRosmini, Antonio. =400 1\$aSerbati, Antonio Rosmini. =400 1\$aRosmini Serbati, Antonio. =670 \\$aKp. Ontologia e morale in Antonio Rosmini / Roberto Nebuloni. - Milano, 1994. =670 \\$aEI. =942 \\$aPERSO_NAME In this case data from authority (field 400) is in bibliographic record in field 100. Like says Katrin if on includeSeeFromInSearches - then "see from" is index with data bibliographic record. Michael I tested on local machines Koha. Update to 18.05.04 and it's the same. Maybe is some ways to hidden this field in config server z39.50? Thanks Michael and Katrin. Regards Kamil -- Sent from: http://koha.1045719.n5.nabble.com/Koha-general-f3047918.html
