From 1cc37081a6444de81fe6351c315a82c7c4f203fe Mon Sep 17 00:00:00 2001 From: Broque Thomas <26755000+Nezreka@users.noreply.github.com> Date: Sun, 10 May 2026 08:53:42 -0700 Subject: [PATCH 1/3] =?UTF-8?q?Fix=20Deezer=20search=20relevance=20?= =?UTF-8?q?=E2=80=94=20issue=20#534?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit # Background User reported (#534) that the import-modal "Search for Match" dialog returned irrelevant results when Deezer was the metadata source. Searching `Dirty White Boy` + `Foreigner` returned 5+ karaoke / "originally performed by" / "in the style of" / "re-recorded" / tribute-band results ranked above the actual Foreigner studio cut from Head Games. User had to scroll past the junk every time, or fall back to iTunes search which is much slower. # Root cause — two layers 1. **Endpoint joined `track + artist` into free-text query.** `/api/deezer/search_tracks` was passing `q=Dirty White Boy Foreigner` to Deezer's `/search/track` API. Deezer fuzzy-matches that string across title / lyrics / artist / album / contributors and orders by global popularity — anything that appears across many compilations outranks the canonical recording. 2. **No local rerank.** None of the search-modal endpoints applied any post-filtering. Deezer's API order shipped straight to the user. # Fix — same architectural shape Cin would build ## Layer 1: field-scoped query at the client boundary `core/deezer_client.py::search_tracks()` now accepts optional `track`, `artist`, `album` kwargs. When provided, builds Deezer's advanced search syntax: `q=track:"X" artist:"Y" album:"Z"`. Massive relevance improvement because each term matches the right field instead of fuzzy-matching everywhere. Backward compat preserved: legacy free-text `query=` callers still work unchanged. Field-scoped path takes precedence when both are provided. Empty input fast-fails without an API call. Embedded double-quotes stripped (Deezer's syntax has no escape mechanism). ## Layer 2: provider-neutral relevance reranker New `core/metadata/relevance.py` module — pure-function rerank over the canonical `Track` dataclass. Composable scoring: - **Cover/karaoke patterns** (multiplier 0.05, effectively buries): matches "karaoke", "originally performed by", "in the style of", "made famous by", "tribute", "vocal version", "backing track", "cover version", "re-recorded", "cover by", etc. across title, album, AND artist fields. Catches the screenshot's exact junk: artist credits like "Pop Music Workshop" / "The Karaoke Channel" / "Foreigner Tribute Band". - **Variant tags** (multiplier 0.4): live / acoustic / demo / instrumental / remix / radio edit / club mix etc. — softer penalty since the user MAY want them. Skipped entirely when the expected_title contains the same tag (so searching "Track (Live)" still ranks Live versions first). - **Exact artist boost** (multiplier 1.5): primary artist exactly matches expected_artist after normalisation. Single strongest signal for "this is the canonical recording". - **Title + artist similarity** via SequenceMatcher (parentheticals + punctuation stripped before comparison). - **Album-type weighting**: album=1.0 > single/ep=0.85 > compilation=0.7. Compilations are more likely tribute / karaoke repackages. Each component is a standalone function so tests pin them individually without standing up the full pipeline. ## Wired at three search-modal endpoints - `/api/deezer/search_tracks` — uses both layers (field-scoped query + rerank). - `/api/itunes/search_tracks` — uses rerank only (iTunes API has no advanced-syntax search, but karaoke / cover variants still leak through and need the local penalty). - `/api/spotify/search_tracks` — already builds field-scoped `track:X artist:Y` query; rerank added as the consistency safety net so all three sources behave the same from the user's perspective. Other Deezer call sites (matching engine, watchlist scanner, auto-import single-track ID) deliberately not touched in this PR — they have their own elaborate scoring pipelines tuned to their specific contexts and aren't surfacing the user-reported issue. Per Cin: "don't refactor beyond what the task requires." # Tests 71 new tests across 3 files: - `tests/metadata/test_relevance.py` (50 tests) — every scoring component pinned individually + the issue #534 screenshot reproduced as a regression test (real Foreigner cut wins after rerank, karaoke variants drop to bottom). - `tests/metadata/test_deezer_search_query.py` (14 tests) — advanced-syntax query construction, field-scoped wiring at the client boundary, free-text path unchanged, kwargs win when ambiguous, limit clamping, cache key consistency. - `tests/imports/test_search_match_endpoints.py` (7 tests) — end-to-end through Flask test client: Deezer endpoint passes kwargs not joined query; karaoke buried at bottom for all three sources; legacy query param still works without rerank. # Verification - 2441 full suite passes (+71 from baseline 2370) - 0 failures (the prior watchdog flake fix held) - Ruff clean across all changed files - JS parses clean (`node -c webui/static/helper.js`) # Architectural standards followed - **Logic at the right boundary.** Query construction lives in the client (every caller benefits from one change). Rerank lives in a neutral module (`core/metadata/relevance.py`) over the canonical `Track` dataclass — works for any source, not Deezer- specific. - **Explicit > implicit.** Every scoring rule has its own named function. Pattern tables are module-level constants tests can introspect. - **Scope discipline.** Audited every Deezer search call site; fixed the user-reported one + the consistent siblings. Did NOT speculatively normalise every Deezer call across the codebase. - **Backward compat.** Free-text `query=` callers untouched. Kwargs added to existing client method signature with safe defaults. - **Tests pin contract at correct boundary.** Pure-function rerank tests don't mock anything; client-query tests stub at `_api_get`; endpoint tests run through the real Flask app. --- core/deezer_client.py | 83 +++- core/metadata/relevance.py | 336 ++++++++++++++++ tests/imports/test_search_match_endpoints.py | 210 ++++++++++ tests/metadata/test_deezer_search_query.py | 194 +++++++++ tests/metadata/test_relevance.py | 398 +++++++++++++++++++ web_server.py | 79 +++- webui/static/helper.js | 1 + 7 files changed, 1282 insertions(+), 19 deletions(-) create mode 100644 core/metadata/relevance.py create mode 100644 tests/imports/test_search_match_endpoints.py create mode 100644 tests/metadata/test_deezer_search_query.py create mode 100644 tests/metadata/test_relevance.py diff --git a/core/deezer_client.py b/core/deezer_client.py index 59330239..663a8b37 100644 --- a/core/deezer_client.py +++ b/core/deezer_client.py @@ -298,10 +298,50 @@ class DeezerClient: # can serve as a drop-in fallback metadata source in SpotifyClient. @rate_limited - def search_tracks(self, query: str, limit: int = 20) -> List[Track]: - """Search for tracks — returns Track dataclass list (metadata source interface)""" + def search_tracks( + self, + query: str = '', + limit: int = 20, + *, + track: Optional[str] = None, + artist: Optional[str] = None, + album: Optional[str] = None, + ) -> List[Track]: + """Search for tracks — returns Track dataclass list (metadata source interface). + + Two call modes: + + 1. **Free-text** (`query='Foreigner Dirty White Boy'`) — legacy + shape, passes the string straight to Deezer's `q` param. + Same behaviour as before, kept for backward compat. + + 2. **Field-scoped** (`track='Dirty White Boy', artist='Foreigner'`) — + builds Deezer's advanced search syntax (`track:"X" artist:"Y"`). + Massively tighter relevance than the free-text path because + the API matches each term in the right field instead of + anywhere across title / lyrics / artist / album / contributors. + Without this, the Deezer ranking buries the canonical track + under karaoke / cover / "originally performed by" variants + — see issue #534. + + Field-scoped form is used whenever ``track`` or ``artist`` is + provided. ``query`` is ignored in that case (the field params + are authoritative).

Deezer's advanced search syntax (`artist:"X"`) is documented as substring match, but in practice it's brittle on artist name variants ("Foreigner [US]", "The Foreigner") and on tracks indexed under non-canonical title spellings. When the advanced query returns nothing, we'd previously land at "No matches" — a regression vs. pre-fix behaviour where free-text would have returned a less-relevant but non-empty set. Fix: when the advanced query returns 0 results AND the caller used field-scoped kwargs, fall back to a free-text join of the same kwargs and re-query. Caller-side rerank still tightens whatever the fallback returns, so the worst-case post-fix behaviour is the pre-fix behaviour — never strictly worse. Pulled the cache + parse + store dance into a private helper (`_search_tracks_with_query`) so the orchestration can call it twice (advanced → fallback) without code duplication. Single API call when the advanced query has results — no wasted requests. Diagnostic logger.debug fires when the fallback triggers so we can see in production whether it's happening (and to which queries). # Tests added (4) - `test_falls_back_to_free_text_when_advanced_empty` — advanced query returns 0, free-text returns hits; client returns the free-text hits + both API calls fire. - `test_no_fallback_when_advanced_query_has_results` — single hit on advanced query → no second API call. - `test_no_fallback_when_legacy_free_text_call` — legacy callers already exhausted the only path; empty result is final. - `test_no_fallback_when_query_unchanged` — empty kwargs path doesn't trigger the fallback branch (used_advanced=False). # Existing tests updated The 4 prior `TestSearchTracksQueryWiring` + `TestSearchTracksCacheKey` tests were stubbing `_api_get` to return empty `{'data': []}` and asserting `assert_called_once`. With the new fallback, those stubs trigger a second API call and the assertions break — even though the FIRST call construction is what the tests cared about. Updated the stubs to return one fake hit so the fallback doesn't fire, and switched to `call_args_list[0]` for first-call inspection. # Verification - 18/18 deezer query tests pass (14 prior + 4 new) - 2445 full suite passes (+4 from prior commit) - Ruff clean --- core/deezer_client.py | 30 ++++- tests/metadata/test_deezer_search_query.py | 127 +++++++++++++++++++-- webui/static/helper.js | 2 +- 3 files changed, 148 insertions(+), 11 deletions(-) diff --git a/core/deezer_client.py b/core/deezer_client.py index 663a8b37..71265a12 100644 --- a/core/deezer_client.py +++ b/core/deezer_client.py @@ -332,7 +332,8 @@ class DeezerClient: """ # Build the actual API query — advanced syntax when callers pass # field hints, raw query otherwise. - if track or artist or album: + used_advanced = bool(track or artist or album) + if used_advanced: api_query = self._build_advanced_query(track=track, artist=artist, album=album) else: api_query = query @@ -340,6 +341,33 @@ class DeezerClient: if not api_query: return [] + tracks = self._search_tracks_with_query(api_query, limit) + + # Safety net: Deezer's advanced syntax is `artist:"X"`-style + # substring match, but in practice it's brittle on artist name + # variants ("Foreigner [US]", "The Foreigner", etc.) and on + # tracks indexed under non-canonical title spellings.

(2) defensive `str()` cast on the worker\'s isrc + mbid extraction. metadata source clients all coerce to string today via `_build_album_track_entry`, but if a future source ever returned int / None for either id the side-effects layer would crash on `.strip()`. cheap insurance. 3 new tests pin: genre aggregation produces deduped insertion-order list, empty when no GENRE tags, isrc/mbid hostile-type input (int, None) coerced to safe string before propagation.', page: 'import' }, { title: 'Auto-Import: SoulSync Standalone Library Now Gets Full Server-Quality Rows', desc: 'soulsync standalone is meant to be a full replacement for plex / jellyfin / navidrome — the imported tracks should land in the db with the same field richness a media server scan would write. they weren\'t. the auto-import context dict (the payload it handed to the post-process pipeline) had no `source` field anywhere, so `record_soulsync_library_entry` couldn\'t pick the right source-id column on the new tracks/albums/artists rows. result: every auto-imported track landed with NULL on `spotify_track_id` / `deezer_id` / `itunes_track_id` / etc. — watchlist scans (which match by stable source IDs) couldn\'t recognise these tracks as already in library and would re-download them on the next pass. fixed by threading `identification[\'source\']` onto the top-level context, plus per-recording IDs (`isrc`, `musicbrainz_recording_id`) onto track_info so picard-tagged libraries land their per-recording metadata directly. also extracted the artist source ID from the metadata source\'s search response (`_search_metadata_source` and `_search_single_track` now pull `best_result.artists[0][\'id\']`) and threaded it through identification → context → standalone library write, so the artists row finally gets its source-ID column populated instead of staying NULL forever. also added `_download_username=\'auto_import\'` so library history shows "Auto-Import" instead of mislabeling every staging import as "Soulseek" (the fallback default), and an "auto_import" → "Auto-Import" mapping in the source-map dicts at side_effects.py to honour it. record_soulsync_library_entry tracks INSERT now also writes `musicbrainz_recording_id` + `isrc` columns directly (matches the navidrome scanner write path). 17 new tests pin: auto-import context carries source for every metadata source (spotify/deezer/itunes/discogs), `_download_username=auto_import`, isrc + mbid pass-through to track_info, album-id back-reference on track_info, artist source-id flows from identification → context (and not from album_id, the prior copy-paste bug), `_search_metadata_source` extracts artist_id from search response, soulsync library writes mbid + isrc to dedicated columns, deezer source maps to deezer_id column, library history + provenance use Auto-Import / auto_import labels.', page: 'import' },
