问题修复

• 403 Forbidden（SearXNG 拒绝 JSON）

  sudo sed -i '/^[[:space:]]\+formats:/a \    - json' data/etc/settings.yml
  
  openwebui 出现这个日志表示搜索链路通了
  Fetching pages: 100%|##########| 8/8 [00:06<00:00,  1.20it/s]

• 解决嵌入模型 NoneType 错误（RAG 功能依赖）

  具体报错
  embedding_function.encode()
  AttributeError: 'NoneType' object has no attribute 'encode'
  
  open-webui 设置 → 嵌入 选择一个可用的嵌入模型（推荐 bge-small-en-v1.5 或 all-MiniLM-L6-v2）
  勾选 绕过嵌入和检索
  设置完，重建索引
