⚡ FileSearchEngine

A blazing-fast, strictly minimalist file search utility for Windows. Built for power users, it features a native global summon hotkey, a multi-threaded architecture, and a "Ghost Engine" that silently synchronizes with the Windows OS in the background.

---

✨ Core Features

• Global OS Summon (Ctrl + Space) Hooks directly into the native Windows API (windows.h). Summon or dismiss the application instantly from anywhere, even while working full-screen in other apps.
• The "Ghost Engine" (Real-Time Sync) Utilizes QFileSystemWatcher to monitor the file system continuously. OS-level file additions, deletions, or modifications are silently hot-swapped into the search index without freezing the UI or requiring a manual rebuild.
• Aggressive Multi-Threading Complete separation of concerns. File indexing (BFS traversal) and query execution operate on dedicated QThread workers, guaranteeing a butter-smooth UI even when parsing millions of files.
• Classic Minimalist UI Designed for maximum information density. Features sharp geometry, strict typography, and a tightly packed table view to maximize vertical screen space.
• Deep Preview Panel Instantly previews images (.png, .jpg, .svg, etc.) and syntax-highlights over 40+ developer text formats (.cpp, .json, .py, .md) directly within the app.
• Rich Hover Tooltips Hovering over deeply packed rows reveals a dynamic HTML-styled card displaying full absolute paths, file sizes, and precise timestamps.

🚀 Getting Started

Prerequisites

• Qt 6.7.3 or higher (installed via the Qt Maintenance Tool).
• MinGW 64-bit compiler.

Building from Source

1. Clone the repository: git clone https://github.com/sekhar-dev79/FileSearchEngine.git Open FileSearchEngine.pro in Qt Creator.
2. Configure the project for your MinGW 64-bit kit.
3. Set the build configuration to Release.
4. Click Build and Run.

Deployment (Standalone Setup)

To create a standalone application folder without relying on Qt Creator:

1. Open the Qt 6.7.3 MinGW Command Prompt.
2. Navigate to your compiled Release folder.
3. Run the deployment tool to fetch all necessary runtime DLLs:

• windeployqt FileSearchEngine.exe (Note: For an even cleaner build, you can safely delete the opengl32sw.dll, Qt6Pdf.dll, and translations folder from the deployment output, as they are not required for this specific widget architecture).
