- Use urllib.parse.quote_plus instead of str.replace(' ', '+') for correct
URL encoding of special chars (&, %, +, #, =)
- Add search_url field to return dict so caller can verify/debug the query
- Add result_count field for quick summary without len(results)
- Deduplicate results by URL via seen_urls set
- Filter cards with both empty title AND empty snippet
- Richer hint string: 'Title (url): snippet[:120]' pipe-separated
- Max-results guard now breaks early (no over-fetching)
- 5 new tests (23→28): URL encoding, result_count, dedup, empty filter, hint format
