Opensolr Changelog — Recent Updates & Improvements

Documentation Mar 15, 2026

Improved Major documentation expansion across Solr error troubleshooting. New in-depth guides for Leader Not Available / Index Fetch Failed, SAXParseException, Missing SearchComponents, NumberFormatException, and ClassNotFoundException. Each guide covers root cause analysis, visual diagrams, and step-by-step fixes. All integrated with the Error Audit for automatic linking.

Improved Updated the Data Ingestion API documentation with full content_type field guidance. The field reference now explains the default behavior, how it controls web vs media display in search results, and how MIME types are auto-detected when using rtf:true. All code examples (cURL, PHP, Python) now include content_type.
Improved Comprehensive code examples added to the Data Ingestion API documentation. Full working PHP and Python examples for both submission methods — JSON body and file upload — with error handling and job status polling. Plus updated cURL examples for every workflow.

New New troubleshooting guide for the Solr "immense term" error. If you have ever seen "Document contains at least one immense term" when indexing, this FAQ walks you through exactly why it happens (untokenized field types treating your entire field value as one giant token) and how to fix it — with visual diagrams, code examples for all four common solutions, and a dedicated section for Drupal / Search API users. Find it under SOLR-Errors in the FAQ.
