How do I set up a private search engine for encrypted browsing and minimal logging?

Setting up a “private search engine” can mean two different things:

1. A privacy-focused search experience using existing engines with minimized tracking/logging.
2. Your own self-hosted search engine for private content or internal use.

If your goal is encrypted browsing + minimal logging, the simplest and safest route is usually the first one.

1) Use HTTPS everywhere

• Turn on HTTPS-Only Mode in your browser.
• Install/enable browser features that upgrade requests to HTTPS.
• Use a DNS provider that supports privacy features, or better, encrypted DNS:
  • DoH (DNS over HTTPS)
  • DoT (DNS over TLS)

2) Use a privacy-preserving search engine

Good options:

• DuckDuckGo
• Startpage
• Brave Search
• SearxNG instances (meta-search, often more private if well-run)

If you want the most control, self-host SearxNG.

Why SearxNG?

• It queries multiple search engines anonymously-ish through your server.
• You control logs, retention, and instance settings.
• It can be configured to minimize cookies and tracking.

3) Self-host SearxNG with minimal logging

A common setup is:

• VPS or home server
• Reverse proxy with HTTPS
• SearxNG container
• Logging disabled or heavily reduced
• Short log retention at the proxy layer

Basic architecture

• Browser → HTTPS → Reverse proxy (Nginx/Caddy) → SearxNG
• Optional: VPN/Tor for accessing the service privately

Logging minimization

Configure:

• No request IP logging, or anonymized IPs
• No query logs, or very short retention
• Disable analytics
• Disable cookies where possible
• Rate limiting to prevent abuse without storing too much data

4) Encrypt traffic

Use:

• TLS certificates from Let’s Encrypt
• HSTS
• Strong cipher defaults in your reverse proxy
• Optional VPN for your access path if you don’t want the service publicly exposed

5) Reduce browser fingerprinting

In the browser:

• Use a privacy-hardened browser profile
• Block third-party cookies
• Disable unnecessary extensions
• Use a consistent window size
• Reduce WebRTC leaks
• Consider Firefox with hardened settings or Tor Browser if anonymity is critical

6) If you need maximum privacy

If your threat model is strong:

• Use Tor Browser
• Access a search engine via Tor
• Avoid logging into personal accounts
• Don’t mix anonymous and identified activity

7) Example: Self-host SearxNG with Docker

Typical components:

• searxng container
• caddy or nginx for TLS
• persistent config volume
• logging disabled or limited

You’d configure:

• public_instance: false
• server.secret_key
• server.base_url
• general.instance_name
• redis optional for caching
• outgoing settings to control upstream requests
• search engine selection and timeouts

8) Operational privacy tips

• Put the server behind a VPN if only you need it
• Use a domain registered with privacy protection
• Pay anonymously if possible, where lawful
• Keep the OS and container images updated
• Restrict admin access with SSH keys and firewall rules
• Separate logs from application data and rotate them aggressively

9) Important limitation

A self-hosted search engine can reduce logging on your side, but the upstream search providers still see queries unless routed through anonymity networks or private infrastructure. If you want stronger privacy, use:

• Tor
• Trusted privacy-preserving upstreams
• Aggressive log minimization

If you want, I can give you either:

1. a simple SearxNG Docker setup, or
2. a more private Tor/VPN-based architecture.
