feat(search): restore collection results in main search

[0xSysR3ll]

Description

Searching for something like "Star Wars Collection" no longer returned movie collections since TMDB's /search/multi route stopped including them. See https://developer.themoviedb.org/reference/search-multi
We weren't calling /search/collection neither, so the only way collections showed up was through the collection banner on a movie page.

How Has This Been Tested?

📝 Walkthrough

Walkthrough

The search flow now queries TMDB collections alongside multi-search results. It maps collections into the search response, documents CollectionResult, supports collection items in the Search component, and updates pagination detection.

Changes

Collection Search

Layer / File(s)	Summary
TMDB collection contracts server/api/themoviedb/interfaces.ts	Adds interfaces for collection search results and paginated collection responses.
TMDB collection client server/api/themoviedb/index.ts	Adds searchCollections, which calls /search/collection and returns an empty result set on errors.
Search route and result exposure server/routes/search.ts, seerr-api.yml, src/components/Search/index.tsx	Runs multi-search and collection search in parallel, maps and combines collection results, updates the API schema, and includes CollectionResult in the Search result type.
Search pagination detection src/hooks/useDiscover.ts	Uses the final page total when available and the final page result count as a fallback.

Estimated code review effort: 3 (Moderate) | ~25 minutes

Merge Risk: 🟡 Moderate · up to 1e50c

The PR adds collection results by combining two paginated searches, but the current result totals and pages do not match the search consumer's pagination assumptions, which can cause incomplete or inconsistent search pages. Ordinary searches also generate an additional TMDB request, increasing quota and availability exposure. Merge should wait for the pagination behavior to be corrected or explicitly accepted, with the added request cost owned.

Poem

A rabbit found collections bright,
And added them to search tonight.
TMDB returned titles in a row,
The route joined them in a steady flow,
While pagination tracked each page just right.

Isn't this calling tmdb.searchCollections() on every page regardless of whether collections have already run out. Once page > collections.total_pages from an earlier response, that call will just return an empty result and it's an extra TMDB request for nothing on every subsequent page. Might be worth caching/skipping once we know collections are exhausted for a given query?

Wdyt @gauthier-th ?

Yeah I see what you mean. How do you see this though ?

Only hit collections on page === 1? They’re almost always a single page anyway.
Or skip once we know they’re exhausted? And use a short-lived server cache keyed by query/language, or the client passing something back.

Maybe not the cleanest way to do this, but it could be done client-side (e.g. if client doesn't receive anymore collection, ask to stop fetching them)

[fallenbagel]

Dug into this a bit. Since the tmdb cache key includes page, it doesn't dedupe here, and the frontend's infinite scroll keeps incrementing page on every scroll tick. So once collections run out, every subsequent scroll fires a real (empty) TMDB request.

I think the cleanest fix would be to cache collections.total_pages per query+language in the tmdb cache, and skip searchCollections once page exceeds it.

Maybe something like:

const tmdbCache = cacheManager.getCache('tmdb');
const pagesKey = `search-collections-pages:${language}:${queryString}`;
const knownTotalPages = tmdbCache.get<number>(pagesKey);

let collections: TmdbSearchCollectionResponse;
if (knownTotalPages !== undefined && page > knownTotalPages) {
  collections = { page, results: [], total_pages: knownTotalPages, total_results: 0 };
} else {
  collections = await tmdb.searchCollections({ query: queryString, page, language });
  tmdbCache.set(pagesKey, collections.total_pages, 300);
}

That would make sude there isnt a need for a client contract change and should be good even for queries with more fhan one oage of collection matches.

Yeah I think I'll implement something like this.

Yes, makes sense
