}🟢search_resources(category, q, limit, cursor)
Search 350 prepared structured resource profiles by category, keyword or declared source hostname without contacting external providers.
输入模式

"description": "Up to 8 whitespace-separated terms within 100 UTF-16 code units including outer whitespace; all terms must match literal case-insensitive substrings across public fields, declared publisher names or declared source hosts, in any order. Example: World Bank public, or worldbank.org public. Hostname matches include label-boundary subdomains; no full URLs, credentials, control characters, stemming or model inference. Ordering: exact resource ID first, then every term matched as a whole word in the title or a declared publisher name, or as a declared source host, then remaining substring matches; ties use stable resource ID order. Ranking is not a quality or ownership assertion."
