- Field registry (services/filter_registry.go): ~55 typed fields —
every book column, file/lifecycle facts, the three HOLDING
STRUCTURES (library, collections with excluded-aware membership,
series with FULL primary+alternate_info membership), and the whole
user-relative class (status, progress, last read, my rating, review,
notes/highlights presence, note/highlight text, time spent, pages
read, collections, added by) reading the VIEWER's rows. Operators
are typed constants; negation is an operator.
- Composed engines (services/filter_query.go): one Go clause builder
over raw pgx feeds the search (identical SearchMediaItemsUnifiedRow
shape), the field-aware suggestions, and a true-COUNT live count.
Mandatory WHERE head everywhere (family lens + integrity facts).
Values are always bound parameters — no user string reaches a
field/operator position, ever.
- Wire: the qf JSON param (validated strictly — unknown
fields/operators/malformed values are 400); qf wins over flat params
on hand-crafted URLs; flat deep links keep working unchanged.
- Endpoints: GET /api/media-items/filter-count (live count);
field-values autocomplete upgraded in place — any registry field
key, qf binds the OTHER rules (symmetric under-filter suggestions,
zero-match values never offered); classic six without a tree keep
their static pinned contract.
- UI: the drawer becomes the rule builder — the ONLY filter UI (templ
markup, Alpine tree state, sanctioned island; grouped field menus,
operator menus with red negations, field-aware value menus, live
count, chips per rule with red negations, URL rehydration, smart
serialization flat-when-simple else qf).
- Tests: composed semantics (AND/OR/negation/nesting/enums/bools/
numbers/dates/empty), every user-relative field class with the
my-data weld (two readers, different worlds), note-text substring
pin (catharsis ≠ Carthage), family lens (hidden libraries nowhere,
403s), suggestion-under-rules exactness, qf validation + precedence,
flat-vs-tree equivalence; registry completeness unit test.
The 9 Batch A facets could not be SET from the web UI, the facets
endpoint had no in-app consumer, and the registry's libraryTypes hints
rendered nowhere. This phase closes all three.
- ONE UNION-ALL sqlc query (FacetCountsUnderFilters) computes all 14
listable facets in a single round trip: each arm omits its OWN
facet's filter block and carries every other registered facet's
block (copied mechanically from SearchMediaItemsUnified) — classic
faceted semantics: with filters active each facet counts under the
others; with none, blocks are neutral and the counts are the v1
global-per-library ones. One query serves both cases. The 14
per-column Batch C queries are deleted.
- Endpoint: no facet param → the new all-facets shape
({facets: {param: [{value, display?, count}]}}), filters bound via
the shared ParseMediaSearchParams, library_id optional (the
All-Libraries view, family lens still enforced); facet=X keeps the
pinned single-facet shape (now routed through the same query with
neutral filters).
- SSR partial GET /media-items/facet-panel: templ renders the drawer's
value lists — registry order, Batch D library-type scoping
(FacetsForLibraryType: manga_type on manga, reading_direction on
manga+comics, narrator on audiobooks; All view = union), prettified
genre labels + language display names, active values marked. Family
lens: out-of-set explicit library_id is 403.
- Drawer wiring: the panel fetches on drawer open and after every
apply with the CURRENT filter query string; a value click toggles
that facet's comma-joined filter (hidden input where the drawer has
no field — same as deep links) and re-applies the form; chips and
URL stay in sync. Values are server-rendered (rendering doctrine);
bookshelf.ts owns only the click/fetch orchestration.
- prettifyGenre moves to internal/utils as the canonical
implementation (services' display enrichment shares it; templ wraps
it; the TS port in bookshelf.ts is unchanged).
- Drift guard extended: FacetCountsUnderFiltersParams must carry every
registry facet's param, the bools as pgtype.Bool.
Tests: under-filter exactness (own-block omission, OR-within,
AND-across), family lens (hidden values absent; 403 on both shapes),
all-shape + pinned-shape coexistence, partial rendering with Batch D
scoping + active marking + 403. Full container suite green except the
documented pre-existing TestAdminCreateUser red.
Phase 1 + backend of Phase 2 of the faceted-navigation plan. One
declarative facet registry (services/facet_registry.go) drives the
bookshelf filter system; a drift-guard unit test reflects over the
generated SearchMediaItemsUnifiedParams so a registry entry and its
sqlc.narg block can never disagree silently.
- Nine new filter params on SearchMediaItemsUnified: story_arc,
imprint, edition (scalar-fuzzy), age_rating, format_group,
manga_type, reading_direction (exact), explicit, abridged
(presence-bound bools). Comma = OR-within multi-select on every
text facet; AND-across-facets unchanged.
- Genre model v2 (user rule: a subgenre is not a genre, it's a tag):
genre_lexicon.go rebuilt as shelf set + subgenre->shelf map;
pickSmartGenre picks direct shelf > mapped subgenre > Fiction floor
> empty (unknown-only stays tags-only). Type-words (Manga, Comics,
Graphic Novel) join the demote list. Both 'adventure' and 'action &
adventure' are shelves — provider data uses both and the verified
traces pin them.
- Language filter UX: comma elements normalize through the ingest
language map, so display names ('English') match rows stored as ISO
codes ('en'). The language autocomplete now serves display names.
- NEW GET /api/media-items/facets?facet=X&library_id=... — registry-
driven value+count listing (14 static per-column queries, family-lens
join); language values carry display names; bool/range facets 400.
- Family-lens gates: an explicit hidden-library library_id is now a
403 on the search endpoints (was a silent empty set) — JSON branch
and HTMX grid partial both.
- handlers.ParseMediaSearchParams is the SINGLE param parser for the
search JSON endpoint and the HTMX grid partial; the HTML branch
previously dropped publisher_filter and narrator_filter silently.
Pins: docs/contract_pins.md changelog entries (additive request
params; new facets endpoint). Tests: facet_registry_test.go (shape +
SQL drift guard + library-type union), series_parsing_test.go genre-v2
cases, facets_integration_test.go (param filtering e2e, counts,
language display, 403s) — container runner.
A2a (metadata round): narrators TEXT[] + narrators_search (tags
pattern: accumulator + GIN pairs) + abridged bool on media_items;
scanner fills from the Libation/ABS sidecar (narrators verbatim,
abridged flag) with audio-payload promotion; editorial fields ride
the real columns while audio_metadata stays scan-derived (duration/
codec/chapters). Detail/edit/save paths carry the fields; the web
edit dialog grows an Audio section (Narrator(s) comma-input, Abridged
toggle, scanned duration read-only); search weights + narrator filter
(word_similarity over narrators_search) + narrator autocomplete added.
A2c (per-media-type wording): copy helpers keyed on format_group —
Listen Now, Mark Complete/Not Complete, Listening Progress, Your
Listening Stats, Time Listening, Time listened (pages tile swapped for
audio), Position H:MM:SS / total H:MM:SS on detail + progress pages
(duration parsed from audio_metadata). Dashboard: system collections
swap to Continue Listening / Recently Listened at DISPLAY time when
the audiobooks library is selected (stored names unchanged; restores
keep working); week card = Listening Time / Sessions / Books Touched;
cover-corner badges identify audiobook (headphones) / comic / manga
cards on mixed grids — books stay unbadged; hover action icon follows
the media type.
A2b (player): the scrubber binds value to the playhead with an explicit
scrub guard (the handle previously froze at its initial max); header
row = reader-style back arrow + Chapter n/total launcher; chapters
open in a floating top-down drawer (current chapter highlighted, page
never shifts); Skip/Speed rows share one label-left layout; honest
wall-clock session accounting (playing-only deltas, paused flush).
A2d (bookmarks): note-bearing time bookmarks ride the existing
media_bookmarks substrate (notes column + sync-aware service already
there) — audio locator convention audio:<seconds>, chapter_number
filled, auto-title '<chapter> — H:MM:SS', capture popover with optional
note, drawer with jump/edit-note/delete. Zero server changes needed.
Verified live on the Libation sample: narrators backfilled by rescan;
PUT edit persisted + overrides detected (narrators, abridged); force
rescan preserved the user edit; reset-to-scanned-of-defaults restored
truth; narrator filter/autocomplete scoped by library; dashboard
listsening wording + badges render; bookmark save with note deduped to
one row.
Adds publisher_filter to SearchMediaItems/SearchMediaItemsUnified
(fuzzy word_similarity against mi.publisher, mirroring genre_filter),
plumbs it through services.SearchParams and the search handler, and
extends the GREATEST relevance ranking to include publisher matches.
Serves the app's author/publisher/genre/tag click-through browses
(UX pass item 5 — publisher was the only facet without a server
filter).
FieldValue struct had no json tags, so Go marshaled fields as uppercase
(Value, Count, Score) but frontend expected lowercase (value, count).
This caused all autocomplete dropdowns (tags, author, series, language)
to silently fail — tagSuggestions[].value was undefined, crashing
toLowerCase() calls and producing empty dropdowns.
Replace direct error equality checks (err == pgx.ErrNoRows, err != http.ErrServerClosed)
with the idiomatic errors.Is() function throughout handlers, services, middleware, and app
startup. This correctly handles wrapped error chains.
Also replace a raw type assertion (*HTTPError) with errors.AsType[*HTTPError]() in the
error handler middleware for consistency.
Additionally, rename shadowed variables for clarity:
- sidecar.go: config -> sidecarConfig, systemConfig (shadowed package-level vars)
- media_scanner.go: uuid -> uuidString (shadowed the uuid package import)
Updated the backend services and handlers to properly detect and pass
the has_cover parameter's validity state to the database layer.
Changes:
- services/search.go: Changed HasCover type from bool to pgtype.Bool
to support 3-state logic (NULL, TRUE, FALSE)
- handlers/media.go: Fixed 3-state detection by checking if has_cover
exists in query params before setting Valid flag
- router/search.go: Fixed 3-state detection to match media.go logic
- router/frontend.go: Use pgtype.Bool{Valid: false} for SSR initial
load to ensure no filtering occurs on first page load
The key fix is detecting whether the has_cover parameter was actually
sent in the request:
- Parameter not sent → pgtype.Bool{Bool: false, Valid: false}
- Parameter sent as "true" → pgtype.Bool{Bool: true, Valid: true}
- Parameter sent as "false" → pgtype.Bool{Bool: false, Valid: true}
Previously, media.go was hardcoding Valid: true, which meant it was
always filtering by has_cover=false (only books without covers) when
the parameter wasn't sent, causing searches to incorrectly return
0 results for queries like "1984".
This ensures consistency between the JSON API endpoint (media.go) and
the HTML endpoint (search.go), and fixes the critical bug where SSR
was returning 0 books on initial page load.
Add shared search method that returns results with count. This method will be used by both JSON API endpoints and HTML rendering for HTMX, avoiding duplicate business logic.
- Extracts common search logic into reusable service method
- Returns search results with total count for pagination
- Follows DRY principle by eliminating duplicated search code
Improve media item search functionality with two key enhancements:
1. Date-prioritized year filtering:
- Prioritize date_published over copyright_year for year range queries
- Fall back to copyright_year when date_published is NULL
- Extract year from date_published timestamp for comparison
2. True exact search matching:
- Replace ILIKE pattern matching with exact equality for quoted queries
- Use search_query directly instead of wildcard pattern for exact matches
- Remove SearchPattern parameter and related wildcard logic
- Add COALESCE handling for author/series NULL values in exact matches
These changes make year filtering more accurate with published dates
and provide genuine exact matching when users wrap queries in quotes.
Refs internal/database/queries/queries.sql:475, internal/services/search.go:62
- Add TagsFilter string to SearchParams struct
- Update dbParams building to include tags_filter
- Add tags case to SearchFieldValues service for autocomplete
- Handle SearchTagsValues query results
Enables the backend service layer to process tag filtering requests
and provide autocomplete suggestions for tag values.
Relates to IMPLEMENTATION_TAGS_FILTER.md Phase 2
Add comment to document that filter parameters use pgtype.Text
with explicit Valid=true flag to ensure proper SQL parameter handling.
This clarifies the intent behind the parameter building logic.
Improves code documentation for future maintenance.
Updates SearchMediaItemsUnified to conditionally set LibraryID parameter
only when it's valid. Previously, the code always set LibraryID in the
dbParams struct, which caused pgx to pass a zero UUID instead of NULL
to PostgreSQL.
New behavior:
- Only sets dbParams.LibraryID when params.LibraryID.Valid is true
- When library_id is empty, LibraryID is omitted from the struct
- Go's zero value + pgx's "field not set" detection = NULL in SQL
Also fixes type mismatches in SearchFieldValues method where
SearchQuery parameter needed explicit pgtype.Text wrapping with
Valid=true flag for proper nullable text handling.
This ensures that omitting the library_id query parameter results in
searching across all libraries, not filtering by zero UUID.
- Create SearchService with SearchMediaItemsUnified method
- Add SearchFieldValues method for autocomplete dropdown population
- Add parseSearchQuery helper for quote detection (exact vs fuzzy search)
- Move all business logic from handler to service layer
- Follow established service pattern (FiltersService, CollectionService)
- Service created inside handler constructor, not in main.go
- SearchParams struct supports all filter types + sort parameter
- FieldSearchParams struct for field-specific autocomplete queries
- Returns FieldValue results with count and similarity scores
This provides a clean service layer abstraction for search operations.
Create new SearchService to encapsulate all search business logic:
Features:
- Unified search combining text search with filters
- Fuzzy matching using pg_trgm word_similarity (threshold: 0.3)
- Exact search when query is wrapped in quotes
- Field-specific autocomplete for dropdowns (author, genre, series, language)
- Proper pagination with configurable limit/offset
Implementation details:
- SearchMediaItems: Routes to SearchMediaItemsUnified query
* Detects exact search by checking for quotes in query
* Builds search pattern for ILIKE matching (%term%)
* Converts string filters to pgtype.Text with proper Valid flags
- SearchFieldValues: Routes to appropriate field-specific query
* Uses switch statement to call correct query based on field_type
* Returns []FieldValue with value, count, and similarity score
* Handles all 4 field types: author, genre, series, language
Design pattern: Service layer separates business logic from handlers,
following project's established architecture (FiltersService, CollectionService).
