I think it is currently impossible to make precise indexing of some MARC fields depending on the value of the 2 indicators (for UNIMARC field 601 for example, which can be a meeting name or an organization name). It can be done presently by modifiying by hand the ...-zebra-....xsl files (adding "and @ind1='1'" in the condition for example), but not automatically when you translate the ...-koha-....xml files to .xsl with xsltproc. So I suppose the / etc / zebradb / xsl / koha-indexdefs-to-zebra.xsl file need to be updated for that. M. Saby
(I won't work on that personaly, but I can test if someone provides a patch)
