From d7ccff138b80adf5fa8181fc27eece1c8bdf407c Mon Sep 17 00:00:00 2001 From: Trenton Holmes <797416+stumpylog@users.noreply.github.com> Date: Mon, 17 Aug 2026 16:30:02 -0700 Subject: [PATCH] feat(search): route parse_user_query through whoosh-compat Rewires parse_user_query() to parse via wc.parse()/tantivy_emit() against the shared FieldRegistry instead of the string-based translate_query() pipeline, so diagnostics map to typed SearchQueryError subclasses (InvalidDateQuery/InvalidNumberQuery/MultipleSearchQueryErrors) and every bad field is reported, not just the first. Marks three pre-existing tests xfail (2 in test_query.py, 1 in test_api_search.py) for confirmed whoosh-compat grammar gaps found while verifying this rewrite: unquoted multi-word date keywords (e.g. `added:previous month`) and RFC3339 T/Z datetime range bounds no longer parse.
