Worked on stabilizing search reliability in the projectblacklight/blacklight repository by addressing a bug in Solr query construction. Focused on backend development using Ruby and Ruby on Rails, the work involved refining the handling of boolean parameters to ensure that empty query strings were skipped in the must clause. This approach prevented malformed queries and reduced the risk of search failures in production environments. To validate the fix, regression tests were added to confirm that empty strings were not included in query construction. The changes enhanced the robustness of API development and contributed to more reliable search functionality overall.
