For DOM indexing, added index_matching_heading option
to create indexes for matching an entire authority
heading -- the index works by indexing a heading
such
150 $aCars$xElectric$zEngland$vScience fiction
as something like
"cars generalsubdiv electric geographicsubdiv england
formsubdiv science fiction"
Also started adjust names of some indexes to conform
to languaged used in the MARC21 and UNIMARC standards, e.g.,
"See" => "See-from"
"See-also" => "See-also-from"
"Conference-name-heading" => "Meeting-name-heading"

Currently, MARC authorities are indexed (assuming Zebra
is used) with Zebra's GRS-1 module. However, it does
not appear to be possible to index phrases that cross
subfield boundaries using the GRS-1 module's records.abs
config file's melm, elm, and xelm directives.
Since it is necessary to be able to efficiently search
an entire authority heading (e.g., to see if a given
bib heading is authorized), I'm proposing a switch
to Zebra's DOM XML filter module, which uses XSLT
to generate the words and phrases to be indexed from the
original MARC XML (or ISO2709) record.
The file authority-zebra-indexdefs.xml is an XSLT stylesheet
to implement the new indexing regime. It is based on the
MARC21 authority record.abs with the following changes:
* addition of 148/448/548
* changed name of "see" indexes to "see-from"
* changed name of "see-also" indexes to "see-also-from"
* added index on the subject thesaurus based on
the 008/11 and 040$f
* added indexes on the full heading
authority-zebra-indexdefs.xml was generated from
authority-koha-indexdefs.xml via the XSL transform
koha-indexdefs-to-zebra.xsl. authority-koha-indexdefs.xml
is the actual master version of the indexing definitions,
and was created to provide a much more compact syntax
over the raw XSLT that is to be passed to Zebra.
An experimental schema for Koha indexing definitions is
under way; my aim is to propose a simple format that can
be readily worked with, and perhaps even generated as
a serialization of indexing definitions that are set up
via administration settings in the Koha database itself.
