From e3076b8d62f7f78025908446269932778a093826 Mon Sep 17 00:00:00 2001 From: Trenton Holmes <797416+stumpylog@users.noreply.github.com> Date: Mon, 6 Apr 2026 13:21:01 -0700 Subject: [PATCH] refactor: remove dead search() method and SearchResults from TantivyBackend All production callers now use search_ids() + highlight_hits(). Migrated 10 tests to search_ids(), removed 5 that tested search()-specific features (score normalization, highlight windowing).
