Prerequisites

You need a local SearXNG instance running. To set it up:

Run SearXNG with Docker

Quick Start

# Create config directory
mkdir -p searxng

# Create config file
tee searxng/settings.yml << EOF
use_default_settings: true

server:
  bind_address: "0.0.0.0"
  secret_key: "CHANGE_THIS_TO_SOMETHING_SECURE"  # Generate a random key
  port: 8080

search:
  safe_search: 0
  formats:
    - html
    - json

engines:
  - name: google
    engine: google
    shortcut: g

  - name: duckduckgo
    engine: duckduckgo
    shortcut: d

  - name: bing
    engine: bing
    shortcut: b

server.limiter: false
EOF

# Start container
docker run -d \
  --name searxng \
  -p 8080:8080 \
  -v "$(pwd)/searxng:/etc/searxng" \
  searxng/searxng

Test Search Function

# Test JSON API with curl
curl -v 'http://localhost:8080/search?q=test&format=json'

# Or visit in browser
http://localhost:8080/search?q=test

Container Management

# Stop container
docker stop searxng

# Remove container
docker rm searxng

# View container logs
docker logs searxng

# Enable auto-start on boot
docker update --restart always searxng

The --restart always flag ensures that:

Container starts automatically when Docker daemon starts
Container restarts automatically if it crashes
Container restarts automatically if it is stopped unless explicitly stopped by user

Custom Configuration

Edit searxng/settings.yml to:

Modify search engine list
Adjust security settings
Configure UI language
Change API limits

For detailed configuration options, see SearXNG Documentation
