Steps to reproduce

图片

✔️ Expected Behavior

class DuckDuckGoSearchResult:
    title: str
    href: str
    body: str


# Expected schema
class DuckDuckGoSearchResponse:
    results: List[DuckDuckGoSearchResult]

❌ Actual Behavior

duckduckgo-search 组件漏洞，ddgs.AnyMethod 返回空结果。

import asyncio
from asyncio import WindowsSelectorEventLoopPolicy

asyncio.set_event_loop_policy(WindowsSelectorEventLoopPolicy())

# v5.1.0
from duckduckgo_search import DDGS


async def main():
    with DDGS(proxies="http://127.0.0.1:2081") as ddgs:
        print(ddgs.text("Chinese", max_results=1))


if __name__ == '__main__':
    asyncio.run(main())
