May 1, 20262026-05 monthly summary: Implemented environment-variable driven DCR rate-limiting configuration and stability improvements for the CourtListener DCR endpoint. Default rate limit adjusted to 20,000 requests per hour to enhance reliability and security. Tests exercised by temporarily setting the limit to 10 in test, then relaxing the limit to validate behavior. The work improves tunability across environments and reduces risk of outages in production.

Nov 1, 2025For 2025-11, delivered structured semantic search support in the CourtListener project by adding query_mode to the SearchQuery model, implementing migrations, updating search utilities, and expanding tests. Admin UI now displays query_mode, and semantic parameter validation helper was introduced with a boolean-safe has_semantic_params refactor, relocated to elasticsearch_utils for reuse. The work enhances search accuracy, differentiates keyword vs semantic queries, and improves maintainability and test coverage.

Feb 1, 2025February 2025 – CourtListener: Implemented the Export Document Coverage Command (export_doc_coverage) to export document coverage statistics to CSV for model pretraining datasets, sourcing data from PostgreSQL or Elasticsearch. Delivered end-to-end data export workflow with CLI options for sleep duration and max Elasticsearch buckets, progress reporting, and flexible yearly/monthly processing optimized for large datasets. Migrated Elasticsearch aggregations to composite aggregations and added batch-by-month processing to improve performance and reliability. Included cleanup/refactors to improve maintainability and alignment with data pipelines. This work enhances data-driven ML workflows and standardizes a reproducible export path across environments.
