[Koha] Koha Digest, Vol 121, Issue 18

[David Cook]

Hi Jesse:

I've read the response from yourself and others, and I agree with Zeno that it would be wise to open a bug on http://bugs.koha-community.org/bugzilla3/.

The reason the keyword searching works is because all text nodes in a MARC record are indexed in the "Any" (ie Keyword) index. The 880 field itself gets no special handling in the current version of biblio-zebra-indexdefs.xsl, which is why searching indexes other than Keyword doesn't work when you're searching for Arabic text stored in the 880.

In my opinion, an elegant solution could theoretically be achieved by something like the following:

<xsl:template match="marc:datafield[@tag='880']">
	<xsl:variable name="linkage" select="substring(marc:subfield[@code='6']",1,3)"/><!-- linkage might contain something like 245 or 260 or 100 -->
	<xsl:call-template name="$linkage" />
</xsl:template> 

However, we don't current use named templates in biblio-zebra-indexdefs.xsl, so that's not possible at the moment. The above is just a hypothetical suggestion that would be easier to maintain and extend.

Glancing at http://bugs.koha-community.org/bugzilla3/show_bug.cgi?id=14217, you might try something like the following in biblio-koha-indexdefs.xml in Koha 3.22:

  <index_subfields tag="880" subfields="a" condition="substring(marc:subfield[@code='6']",1,3) = 245">
    <target_index>Title-cover:w</target_index>
    <target_index>Title-cover:p</target_index>
    <target_index>Title-cover:s</target_index>
    <target_index>Title:w</target_index>
    <target_index>Title:p</target_index>
    <target_index>Title:s</target_index>
  </index_subfields>

Unfortunately, this convention requires you to make a block for every index linkage you need. That is, you'll need to do the same for 245, 260, 100, etc. It'll also be more difficult to maintain in the long-run, so it would be wise to locate the 880 near its linked field in the biblio-koha-indexdefs.xml file, so as to prevent deviations between how the fields are indexed.

Of course, since you're probably only trying to provide access to a handful of commonly used fields, this shouldn't be too laborious of a process.

It is possible to fix your situation one way or another, Jesse. XSLT is powerful and DOM indexing is quite flexible as a result.
