Can I Self-Host My Own Search Engine? A Deep Dive into SearXNG

In an age where data privacy is increasingly important, many tech enthusiasts are looking for ways to reduce their reliance on big tech companies. One question that often comes up is, “Can I self-host my own search engine?” The answer is a resounding yes, and one of the best solutions for this is SearXNG.

What is SearXNG?

SearXNG is a free, open-source metasearch engine that aggregates results from various search engines while respecting user privacy. It acts as a proxy between you and search engines, which means:

Your searches aren’t tracked by the big search providers.
You get a wide range of results from multiple sources.
You have control over your search experience and data.

Why Self-Host SearXNG?

Self-hosting SearXNG offers several advantages:

Complete Privacy: Your search queries never leave your own server.
Customization: You can tailor the search engine to your preferences.
No Ads or Tracking: Enjoy a clean, unbiased search experience.
Learning Opportunity: Gain valuable experience in server management and web services.

How to Self-Host SearXNG

Let’s walk through the process of setting up your own instance of SearXNG. This guide assumes you’re using a Unix-like system (Linux or macOS).

Prerequisites

Step-by-Step Installation Guide

Update Your System
```
sudo apt update && sudo apt upgrade -y
```

Install Required Packages

sudo apt install -y python3-pip python3-venv git build-essential libxslt-dev zlib1g-dev libffi-dev libssl-dev

Create a SearXNG User

sudo useradd --shell /bin/bash --system --create-home searxng

Clone the SearXNG Repository

sudo -u searxng -i
git clone https://github.com/searxng/searxng.git
cd searxng

Create a Virtual Environment

python3 -m venv searxng-venv
source searxng-venv/bin/activate

Install SearXNG

pip install --upgrade pip
pip install -e .

Create Configuration File

sed -i -e "s/ultrasecretkey/$(openssl rand -hex 32)/g" searx/settings.yml

Run SearXNG
```
python searx/webapp.py
```
Your SearXNG instance should now be running on http://localhost:8888.

Set Up a Reverse Proxy (Optional but Recommended)

For better security and to use a domain name, set up Nginx as a reverse proxy:

sudo apt install nginx

Create a new Nginx configuration file:

sudo nano /etc/nginx/sites-available/searxng

Add the following content (replace your_domain.com with your actual domain):

server {
    listen 80;
    server_name your_domain.com;

    location / {
        proxy_pass http://127.0.0.1:8888;
        proxy_set_header Host $host;
        proxy_set_header X-Real-IP $remote_addr;
    }
}

Enable the configuration:

sudo ln -s /etc/nginx/sites-available/searxng /etc/nginx/sites-enabled/
sudo nginx -t
sudo systemctl restart nginx

Secure with SSL (Recommended)

Use Certbot to obtain an SSL certificate:

sudo apt install certbot python3-certbot-nginx
sudo certbot --nginx -d your_domain.com

Maintaining Your SearXNG Instance

To keep your SearXNG instance running smoothly:

Regularly update SearXNG and its dependencies.
Monitor server resources to ensure optimal performance.
Keep your server’s operating system and software up to date.
Regularly back up your SearXNG configuration and data.
