GET /datasets/techstack/search

Search the website tech-stack dataset

Searches the website tech-stack index (dataset id enum value `techstack`) — one record per site listing the web technologies it is built with (frameworks, CMS, e-commerce, analytics, CDNs, servers, and more), BuiltWith / Wappalyzer-style. The reverse-index filters are the point: repeat `technology` to require several at once (AND), `any_of` to match at least one (OR), and `not` to exclude — e.g. sites on `Shopify` and `Klaviyo` but not `Recharge`. Sort enum: `relevance`, `rank_asc`, `tech_count_desc`, `domain_asc`, `crawled_desc`. render_tier enum: `http`, `browser`.
