Jul 1, 20252025-07 Elasticsearch (elastic/elasticsearch) monthly summary: Strengthened search integrity, improved query performance, and stabilized telemetry tests. Key deliverables include: - Preventing search functions from operating on non-STANDARD index fields introduced by a LOOKUP JOIN RHS (KNN and MATCH now respect index type), reducing invalid search results. - Pruning columns added by InlineJoin to eliminate unnecessary aggregations and boost query performance. - Reenabled and stabilized InlineStats telemetry tests after refactoring to ensure correct planning and expected output validation. Overall impact includes improved search accuracy, faster query execution, and higher confidence in telemetry-driven validation, enabling safer releases and quicker feedback loops.
