--- Comment #20 from Galen Charlton <gmcharlt at gmail.com> ---
Here is a summary for documentation purposes of the patches that have been
signed off:

This is a series of patches implementing DOM-filter indexing for 
bibliographic records.  Currently this series of patches does the
following:

[1] Adds a Makefile.PL option to enable DOM filter indexing
[2] Adds a utility for converting a record.abs index definitions
    to DOM-style definitions
[3] Includes DOM-style index definitions for MARC21 bibs that are
    equivalent to the legacy record.abs, with the exception that
    phrases can span subfield boundaries.

To test this on an existing database, some variation of the following
procedure should work:

[1] perl Makefile.PL and choose to enable DOM indexing of bibs
[2] If the index defintions have been customized, use
make_zebra_dom_cfg_from_record_abs
    and the koha-indexdefs-to-zebra.xsl stylesheet to generate a
    an updated biblio-zebra-indexdefs.xsl
[3] make
[4] make update_zebra_conf

This patch series also includes the following related changes:

[1] The -a and -x options to rebuild_zebra.pl are no longer mutually exclusive.
[2] The title phrase rank 3 field weight has been replaced by Title-cover. 
This prevents a side effect of DOM indexing (where the DOM-filter equivalent of
record.abs melm XXX indexes the entire field as a unit, not each subfield
separately) from given the statement of responsibility in the 245$c undue
weight in relevance ranking.
[3] Some comments were added regarding the potential future deprecation of the
use of Zebra's GRS-1 filter.
