🧠 Smart Search AI — Self-Learning Search Plugin for WordPress

Smart Search AI is a lightweight, self-improving search engine built in pure PHP + MySQL, seamlessly integrating with the default WordPress search.
It continuously analyzes user queries and clicks to make search results smarter and more relevant — all without any external APIs or cloud AI.

🚀 Features

✅ Self-Learning Algorithm — every search and click updates internal word weights in real time.
✅ Relevance Boosting — results are sorted by both word relevance and click frequency.
✅ No Dependencies — no API keys, no external AI, no bloat — works entirely on your server.
✅ Real-Time Statistics — admin dashboard with top words and latest search logs.
✅ Privacy-Friendly — all data stays within your WordPress database.

🧩 How It Works

1. A visitor searches for something using the default WordPress search.
2. The plugin logs the query and increases the weight of words found in it.
3. When a visitor clicks a result, the plugin strengthens the weight of those words even more.
4. Future searches are automatically ranked higher for frequently clicked or relevant words.

⚙️ Installation

1. Upload the plugin folder to /wp-content/plugins/smart-search-ai/
2. Activate Smart Search AI from the WordPress admin panel.
3. Use the default search — the plugin will start learning automatically.
