>Subject: [PATCH] Bug 26472: Configure Elasticsearch for better alphabetic
> sorting
>
>This enhancement configures the ICU collation keyword plugin used by Elasticsearch for sorting to better handle punctuation and whitespace in sort fields.
>
>Details at: https://www.elastic.co/guide/en/elasticsearch/plugins/current/analysis-icu-collation-keyword-field.html
>
>To test:
>
>1. Create three authority records with the following values:
>
>150 $a Science.
>150 $a Science $v B.
>150 $a Science $v C.
>
>2. Search for your authority records with "Science" in "Heading A-Z" order
>
>The search results will likely be in this order:
>
>    1. Science B.
>    2. Science C.
>    3. Science.
>
>This is an unexpected order
>
>3. Apply the patch and reindex
>
>sudo koha-elasticsearch --rebuild -r <instancename>
>
>4. Search for your authority records again with "Science" in "Heading A-Z" order
>
>Confirm your search results show in the correct order.
>
>    1. Science.
>    2. Science B.
>    3. Science C.
