From 01aaf386b197cc7b758642d8ad992283dd4327e0 Mon Sep 17 00:00:00 2001 From: Jesse Robbins Date: Fri, 10 Apr 2026 11:33:28 -0700 Subject: [PATCH 1/4] Revert DuckDB search from regexp_matches to ILIKE for performance The regexp_matches approach caused significant performance regression in TUI fast search (Parquet scans). ILIKE is natively optimized by DuckDB for Parquet columnar scans. FTS5 deep search path remains unchanged for body text accuracy.
