[Koha-devel] Default indexing and search options for 3.14

[Martin Renvoize]

DOM and ICU are definitely the newer technologies and have been built
explicitly to fix a number of shortcomings in GRS-1 and chr.

As Ian mentioned we have been slowly moving all our customers to using this
combination, and admittedly it has been a relatively painful process whilst
we iron out the various bugs.  However, for MARC21 at least, most of these
are now fixed, and trying to support both sets of configs is only going to
be a burden in the future.  Whilst we support the both DOM and GRS-1 we
will inevitably keep getting the configurations are out of sync, and should
we try to keep them in sync we will be limiting the DOM config with the
limitations of GRS-1.

My vote is to make the move to DOM with ICU, advocating that getting it
right once is much easier than trying to maintain two disparate
configurations.
