Find sources discussing a topic

Build a first reading list for market research, a technology landscape, or a literature review.

SELECT DISTINCT s.score, c.url,
       node_text(s.capture_id, query_selector(s.capture_id, 'h1')) AS heading
FROM search('battery recycling') AS s
INNER JOIN captures AS c ON c.capture_id = s.capture_id
ORDER BY s.score DESC, c.url, heading
LIMIT 20;

What you get

Up to 20 source links and headings, ordered by relevance. A page can appear more than once if its content changed between captures.

https://example.com/research/recycling	Battery recycling methods

Adapt it

Replace battery recycling with your topic. Try individual terms to understand what they contribute to the results.

Notes

Search matches any normalized non-stopword token. It is neither exact-phrase nor semantic search. A missing h1 produces no heading, not proof that the page has no relevant content.
