Hi. Going forward we expect to use DOM and ICU with MARC21. Broadly we are getting good behaviour. However at present searching authorities gives the same results for "starts with" and "contains". On some installations we have that are older versions of zebra and Koha and probably not using DOM or ICU the two authority searches do give results that are more-expected. Colin has been trying to track down why "starts with" is treated the same as "contains", but it would be good to have this resolved so we are improving searching for all and not breaking existing functions. If anyone can shine any light on this problem or a solution that would be most helpful. +1 for the roadmap. Ian On 24/10/2013 15:44, Galen Charlton wrote:
Hi,
I would like to have a discussion regarding making certain options the default for new installations of Koha 3.14 and deprecating other options. Here's the list of proposals:
Enable DOM mode by default for both bibs and authorities -----------------------------------------------------------------------------------
Now that MARC21, NORMARC, and UNIMARC have DOM indexing configurations available, this is now possible.
Deprecating the GRS-1 filter -----------------------------------------
Giving that DOM has significant advantages of GRS-1 in its flexibility, and as the DOM filter would be required for non-MARC metadata support by Zebra, I propose that we announce a deprecation of the GRS-1 configuration with it to be removed by 3.16. I foresee several features coming down the pike for 3.16 that would require a reindexing during upgrade anyway, so switching to DOM for 3.16 would not impose a burden that wouldn't be present anyway.
Enable QueryParser by default ---------------------------------------------
Bug 10542 might be a blocker for this, and doing something about bug 10831 would be nice in order to do this.
Deprecating non-QueryParser mode ---------------------------------------------------
Removing the non-QueryParser code would go a long way towards easing the rewrite of C4::Search.
Enable ICU by default -------------------------------
This was discussed during hackfest. One precondition I see is that bug 10729 would have to pass QA
