功能

通过 SearXNG 搜索引擎获取网页结果，使用 VLM 对网页内容进行智能分析和结构化提取。 具备双层缓存机制（向量语义缓存 + 数据库缓存）。

调用方式

from services.websearch_service.client import WebSearchClient

client = WebSearchClient()

健康检查

status = client.health_check()

联网搜索（自动使用缓存）

result = client.search("Python async编程", max_results=5)

强制刷新（忽略缓存）

result = client.search("最新AI技术", max_results=3, force_refresh=True) result2 = client.search("openai", max_results=3, force_refresh=True)

获取结果

for r in result["results"]: if r.get("success") and r.get("data"): print(r["title"], r["data"]["main_content"])

for r in result2["results"]: if r.get("success") and r.get("data"): print(r["title"], r["data"]["main_content"])

返回格式
