------------------------------------
Summary: UnsupportedOperationException in SpellCheckComponent when
Sorting Collations
Key: SOLR-17870
URL: https://issues.apache.org/jira/browse/SOLR-17870
Project: Solr
Issue Type: Bug
Components: spellchecker
Affects Versions: 9.6.1
Reporter: Puneet Sharma
Attachments: image-2025-08-20-11-34-37-839.png
When executing a search query with spell checking enabled
({{{}spellcheck=true{}}}), Solr throws a
{{{}java.lang.UnsupportedOperationException{}}}. This occurs because the
{{SpellCheckComponent}} attempts to sort an immutable list of spellcheck
collations.
Environment:
Solr version - 9.6.1
Steps to reproduce
# Set up a SolrCloud collection with the {{SpellCheckComponent}} configured in
the request handler (e.g., the default {{/browse}} handler).
# Index documents that would allow the spell checker to generate suggestions
(collations).
# Execute a search query containing a typo and the parameter
{{spellcheck=true}}
{{Query:}}
{{}}
{{/browse?q=xbox+seris+s*&spellcheck=true&..}}
