Solr Image - ICUFoldingFilterFactory values for indexing diacritics missing from schema.xml

[g7morris]

Issue description

On the current Solr Image, ICUFoldingFilterFactory values for indexing diacritics are missing from schema.xml. This will mean potentially improper or missing necessary indexing of any object with accents, symbols etc in it's metadata.

Given that the necessary SOLR libraries are indeed installed https://github.com/Islandora-Collaboration-Group/isle-solr/blob/27c1dc649d0d296af37db38c3e82539e4a427e86/Dockerfile (see lines 37 & 38), this should hopefully be easy to fix by adding in the appropriate lines to the schema.xml file.

TO DO / Steps to resolve the issue

• Review https://github.com/discoverygarden/basic-solr-config/blob/4.10.x/conf/schema.xml

• Review Example attached schema_with_icu.txt. I've commented in the appropriate areas with <-- ISLE customized 2018 -->

• Determine how during the Solr image build process, to add / append etc the following:

  • Between the current Lines 164 and 165 add: <filter class="solr.ICUFoldingFilterFactory"/>

  • Between the current Lines 173 and 174 add: <filter class="solr.ICUFoldingFilterFactory"/>

@br2490 I'll leave it to you how this process should work in the Dockerfile e.g. use of echo or other tools / methods.

@g7morris And line 193 or does that line not get the same treatment?

[g7morris]

@br2490 Good question but I don't think so. At least in my experience (so far) only the above mentioned lines aka Solr fieldTypes need those extra lines. If endusers need more Solr fieldtypes to be indexed in this manner, they can bind-mount their versions. I'm just after getting a basic out of the box experience.

@br2490 schema.xml looks good! Ship it! (thanks)

@br2490 I'm seeing the changes and will close the ticket. If anyone else finds that diacritics are still not working somehow, please test and open a new ticket.
