fix(api): include filename in books page search - #2487
Conversation
The command-palette search on /api/v1/books/page (the `query` parameter, handled by BookSearchSpecification.matching) matched only on metadata title, series name, ISBN, ASIN, authors, categories, and tags. Filename was never considered, a regression from the previous client-side search that let users find books by their file name. Add a correlated EXISTS subquery over BookFileEntity so a book matches when any of its files' names contain the query, mirroring the existing collectionMatches helper. EXISTS keeps a book with multiple matching files from being returned more than once. Cover the behavior with BookSearchSpecificationTest against H2: filename match when title/author/series do not match, case insensitivity, no false positives, and single-result dedup for multi-file books.

WalkthroughBook search now includes case-insensitive matches against associated file names. New H2 tests cover matching, no matches, case handling, blank queries, and duplicate results. ChangesBook Search Enhancement
Estimated code review effort: 2 (Simple) | ~10 minutes Merge Risk: 🔵 Low · up to The endpoint now finds visible books by filename, but case-insensitive matching may behave inconsistently under certain locale settings. The change is otherwise localized and preserves authorization and visibility rules, so it is mergeable with owner awareness or follow-up to make casing behavior locale-stable.

Learning: In backend unit tests (Java files under backend/src/test/java), do not flag hardcoded placeholder filesystem paths (e.g., setting LibraryPathEntity.path = "/example") as violations when the value is intentionally unused for filesystem access. Only suppress the "no hardcoded paths" concern if the test does not perform any filesystem/network IO using that path (no reads/writes/Files.* calls or code paths that access the filesystem with that value); if the placeholder is actually used to touch the filesystem, flag it.

22-22: LGTM!
Persist two books in the null/blank-query test and assert both are returned with containsExactlyInAnyOrder. The prior single-book, contains() assertion could not catch a query that returned only one book instead of every persisted book for a blank query.

Description
The command-palette search on
GET /api/v1/books/page(itsqueryparameter) no longer matched a book's filename, a regression from the previous client-side search. The spec behind that endpoint,BookSearchSpecification.matching, searched title, series name, ISBN, ASIN, authors, categories, and tags, but never the filename. This restores filename matching.Linked Issue
Fixes #2293
Changes
EXISTSsubquery overBookFileEntitytoBookSearchSpecification.matching, matching when any of a book's file names contain the query (case-insensitive). Mirrors the existingcollectionMatcheshelper;EXISTSavoids returning a multi-file book more than once.BookSearchSpecificationTest(H2 integration test): filename match when title/author/series don't match, case-insensitivity, no false positives, and multi-file dedup.Manual Testing Steps
zqxwvtokendoes not appear in its embedded title (Printable 4-page SVG (Letter)), then rescanned the library.GET /api/v1/books/page?query=zqxwvtokenreturns the book. Because the token exists only in the filename, this confirms the filename match.GET /api/v1/books/page?query=printable(title) returns the book;?query=notpresentxyzreturns nothing. Confirms existing search still works and there are no false positives.AI Disclosure
Claude (Claude Code) - investigated the regression and traced the real endpoint code path, wrote the spec change and the H2 integration test, and ran the backend checks and a live end-to-end verification. I reviewed and understand all changes.
