## When to prefer this

Choose this endpoint when you specifically need Hacker News discussion results relevant to research teams, and want live web-indexed results rather than the official HN Algolia search API. It is particularly useful when you want results filtered through a research-team lens and need a pay-per-call model without API key setup.

## Known failure modes

- No results returned if query is too niche or Bing has no indexed HN matches
- Results may be outdated if Bing has not recently crawled relevant HN threads
- Query exceeding Bing's effective search scope may return generic or off-topic results
- max_results values outside 1-10 range will be rejected by schema validation
