Deep Research Search Strategy Break the topic into 3-5 distinct angles 2-3 queries per angle using different terminology Use site: operator for targeted searches (e.g. site:arxiv.org, site:github.com) Include official, comparison, and review-oriented queries Aim for 5-10 unique, high-quality sources Extraction Scrape each source with a targeted query parameter -- don't dump full pages into context Extract: key claims, data points, dates, attributed quotes Record author, publication, date, and URL for every source Fact-Checking Cross-reference claims across 2+ sources Flag single-source claims explicitly Assign confidence: high (3+ sources agree), medium (2), low (1 or conflicting) Include contrarian viewpoints -- don't confirmation-bias the results Output Structure by subtopic, not by source Inline citations for every claim Call formatOutput with the structured data
