SearXNG Search Skill

Privacy-respecting web search powered by a local SearXNG metasearch engine.

Overview

This skill provides fast, private web search by running a local SearXNG instance. It aggregates results from 70+ search engines without tracking or profiling.

Private: No tracking, no profiling, no data collection
Fast: Local instance for quick responses
Comprehensive: Aggregates results from 70+ search engines
Precise: Category-based filtering (general, images, videos, news, files, etc.)
Multi-language: Supports English, Chinese, Japanese, and more

First-time Deployment

If you already have SearXNG running, skip to Configuration.

Prerequisites

Docker and Docker Compose installed
A directory for SearXNG data (this guide uses ~/service/searxng)

1. Create project directory

mkdir -p ~/service/searxng/config ~/service/searxng/data
cd ~/service/searxng

2. Create `docker-compose.yml`

version: '3.8'
services:
  searxng:
    image: docker.io/searxng/searxng:latest
    container_name: searxng
    restart: unless-stopped
    ports:
      - "8888:8080"
    volumes:
      - "./config:/etc/searxng:rw"
      - "./data:/var/cache/searxng:rw"
    environment:
      - SEARXNG_BASE_URL=http://localhost:8888/
    cap_drop:
      - ALL
    cap_add:
      - CHOWN
      - SETGID
      - SETUID

3. Create `config/settings.yml`

use_default_settings: true

server:
  secret_key: "CHANGE_ME_TO_A_RANDOM_STRING"   # ← 必须修改！
  limiter: false        # 本地使用可关闭限流
  image_proxy: true
  port: 8080
  bind_address: "0.0.0.0"

search:
  safe_search: 0
  autocomplete: "google"
  default_lang: "en"
  formats:
    - html
    - json              # ← 必须启用 JSON，脚本依赖此格式

ui:
  default_theme: simple
  theme_args:
    simple_style: auto

重要: secret_key 必须替换为一个随机字符串。可以用以下命令生成：
openssl rand -hex 32

4. Start the service

cd ~/service/searxng
docker compose up -d

5. Verify

# 检查容器运行状态
docker compose ps

# 测试 Web 界面
curl -s http://localhost:8888/ | grep -o "searxng" && echo "OK"

# 测试 JSON API（脚本依赖此接口）
curl -s -X POST http://localhost:8888/search \
  -d 'q=test&format=json&categories=general' \
  -H 'Content-Type: application/x-www-form-urlencoded' | python3 -m json.tool | head -5

Troubleshooting

问题	解决方法
端口 8888 被占用	修改 `docker-compose.yml` 中的端口映射，如 `"9999:8080"`
JSON API 返回 HTML	确认 `settings.yml` 的 `search.formats` 包含 `json`
容器启动后立即退出	`docker compose logs` 查看错误，通常是 `secret_key` 未设置
搜索无结果	部分引擎有区域限制，检查网络环境或换用其他引擎

Optional: Enable rate limiting (公网部署时)

如果将 SearXNG 暴露到公网，建议启用 limiter + Valkey：

# docker-compose.yml 追加
  valkey:
    image: docker.io/valkey/valkey:8-alpine
    container_name: valkey
    restart: unless-stopped
    command: valkey-server --save 30 1 --loglevel warning
    volumes:
      - "./valkey-data:/data"

# settings.yml 修改
server:
  limiter: true

valkey:
  url: valkey://valkey:6379/0
