⁠What's Included

• Official Elasticsearch base image
• ICU Analysis plugin for advanced text analysis
• Support for Unicode normalization and collation
• Optimized for Koha ILS search requirements

⁠Why This Image?

Koha requires the ICU analysis plugin installed. Installing the plugin requires network access and is subject to temporal failures. This image bundles the required plugin on top of the official Elasticsearch images to minimize such issues for Koha deployments.
