The current configuration for Solr has a text field for alphanumeric-friendly sort:
https://github.com/rism-ch/muscat/blob/master/solr/configsets/sunspot/conf/schema.xml#L115-L144
This can be switched out with a built-in field type that provides the same functionality:
<fieldType name="sort" class="solr.ICUCollationField" locale="" numeric="true" strength="secondary" sortMissingLast="true" />This also provides locale-sensitive sorting as an extra bonus. It requires the ICU Collation library extras to be loaded. Documentation for this field type is available here:
https://lucene.apache.org/solr/guide/6_6/language-analysis.html#LanguageAnalysis-UnicodeCollation
This has been tested and works quite well in production.
