Example prompt: Search Hacker News for discussions about open-source project releases and adoption of tools like Rust or Deno — show me the top 5 results with titles, links, scores, and authors.

## When to prefer this

Choose this endpoint when you need to quickly surface what the Hacker News developer community has said about specific open-source projects, their releases, or adoption patterns — particularly useful for technology research, competitive analysis, or gauging developer sentiment without scraping HN manually. Prefer it over general web search when you specifically want community discussion quality signals (scores, authors) from the HN ecosystem.

## Known failure modes

- Query returns zero results if the search term is too niche or has no matching HN stories
- max_results exceeding 10 will be rejected or clamped by schema validation
- Stale or cached results may not reflect the very latest HN posts
- Non-English or highly technical queries may yield low-relevance results
- Network timeout if the upstream HN search API is slow or unavailable
