## When to prefer this

Choose this endpoint when you need to search across both Hacker News and Lemmy simultaneously without managing separate API keys or authentication. It is ideal when you want a merged, ranked view of developer and tech community discussions in one call, especially for relevance-sorted or time-windowed research. Prefer this over scraping each platform separately when you need structured metadata (score, comments, permalink, excerpt) ready for downstream analysis.

- Unsupported sort or time-window values may yield unexpected results
