A compact, open-source Windows launcher called Fluent Search is turning heads for its ability to index hundreds of thousands of files in minutes and deliver near-instant search results, offering a Spotlight-like experience without the overhead of Microsoft’s built-in search. In a recent hands-on test by MakeUseOf, the app indexed over 440,000 files across two drives in mere minutes—a stark contrast to the sluggish Windows Search indexer that many users have learned to disable outright.
Fluent Search isn’t brand new, but renewed attention from the tech press has put it back on the radar of keyboard-first power users. It joins a crowded field of third-party launchers—PowerToys Run, Everything, Flow Launcher—yet stands apart with its own indexing engine, a plugin ecosystem, and a flexible automation system called Tasks.
What Fluent Search Actually Does
At its core, Fluent Search is a keyboard-triggered overlay. Press a customizable hotkey, start typing, and it surfaces matches from a broad set of domains:
- Local files (full-text or filename only, depending on the chosen indexer backend)
- Running applications and their open windows
- Browser tabs across Chrome, Edge, Firefox, and others
- System settings and Control Panel items
- Custom plugins (currency conversion, clipboard history, dictionary, translator)
- Automated Tasks that chain multiple actions to a single trigger
The app can lean on its own indexer, or it can integrate with existing ones—Windows Search or Everything (the ultra-fast filename searcher). This flexibility means you’re not locked into one approach; you can get full-text searching when you need it, or raw filename speed when you don’t.
According to the official documentation, Fluent Search keeps all indexed data on-device. It doesn’t send search queries off to the cloud, a point of interest for anyone who already disabled Windows Search’s web-connected features for privacy reasons.
Why It’s Getting Attention Now
The recent MakeUseOf write-up highlighted something battery-conscious users have long wanted: a fast search that doesn’t punish your laptop. Windows Search is notoriously resource-hungry—so much so that guides on disabling it are common. Fluent Search’s indexer, by comparison, completed a full scan of over 560,000 files in minutes without causing noticeable system strain, the reviewer reported. That performance claim is anecdotal (your mileage will vary based on drive type, file count, and configuration), but it echoes feedback from the project’s community.
Coupled with an installer size often described as “about 80 MB”—though actual builds can range from roughly 70 MB to over 180 MB depending on the release channel—the app feels lightweight next to bloated system tools. Release notes show the developer has actively trimmed memory usage and install footprint over recent versions.
Setting It Up: A Walkthrough
Getting started is straightforward, but the choices you make during setup matter. Here’s a practical path:
- Download from the project’s website or the Microsoft Store. Both versions are functionally identical, but the Store variant sandboxes the app more tightly, which may matter in managed environments.
- Pick your hotkey carefully. The default Alt+Space works, but that shortcut is also used by other tools; conflict avoidance is key.
- Decide on an indexer. The built-in indexer gives you full-text search; opting for Everything as a backend prioritizes filename speed. You can change this later.
- Allow or deny crash reporting. The final step of the wizard asks if you want to send crash data to the developer. Declining keeps everything local.
If you install the background indexer service, it will kick off immediately and post a notification when the initial scan finishes. The numbers reported by MakeUseOf—440,000 files in minutes—were on a dual-drive system; older spinning disks or vast file collections will take longer.
Once running, the settings menu (right-click the system-tray icon) opens a deep configuration tree. From there you can toggle plugins, adjust the indexer’s scope, create Tasks, and tweak the UI.
How It Stacks Up Against the Competition
Fluent Search isn’t the only game in town. Here’s how it compares to the two most common alternatives:
| Feature | Fluent Search | PowerToys Run | Everything |
|---|---|---|---|
| Core function | Full launcher with indexer and automation | Lightweight launcher, part of PowerToys suite | Ultra-fast filename search (NTFS journal) |
| Indexer | Built-in full-text, or plug into Windows Search / Everything | Uses Windows Search index | Own indexer (filenames only) |
| Browser tab search | Supported, but compatibility varies by browser | Not built in | Not applicable |
| Plugin ecosystem | Growing (23+ plugins) | Community-driven, smaller set | Third-party add-ons possible |
| Automation (Tasks) | Yes, with trigger-action chaining | No | No |
| Resource usage | ~70–180 MB installer; RAM in tens to low hundreds of MB | Lightweight, part of PowerToys (~100 MB suite) | Extremely small, minimal RAM |
Many power users run these tools side by side. A common strategy: use PowerToys Run for quick app launches and Everything for raw filename searches, then lean on Fluent Search when you want a unified overlay that pulls in browser tabs, system settings, and custom Tasks.
What to Watch Out For
No third-party tool is a drop-in replacement without edges. Here are the real-world limits and risks, drawn from the project’s own documentation and community reports:
- Browser tab search isn’t universal. While Chrome, Edge, and Firefox are listed, support is spotty—some users report incomplete results. Test with your preferred browser before building workflows around it.
- Plugin security. The plugin system is open, and third-party code can increase your attack surface. In sensitive environments, audit plugin code or restrict to trusted sources.
- Background service requires scrutiny. The optional indexer runs as a privileged service. On multi-user or corporate machines, admins should verify its permission model and storage locations (typically ProgramData or AppData).
- Installer size varies. Don’t anchor on a single megabyte figure. Check the release notes for the build you’re using; the project has made large cuts in recent updates.
- Resource use depends on configuration. With the indexer active and several plugins loaded, memory usage can creep into the low hundreds of megabytes. Gaming mode and the “Reduce memory usage” setting help, but they’re manual toggles.
Should You Install It?
Fluent Search is a compelling upgrade for three types of Windows users:
- Keyboard-centric productivity seekers who want one hotkey to reach files, open tabs, and settings.
- Privacy-focused users who’ve disabled Windows Search and need a local-only indexer.
- Automation tinkerers who will actually use Tasks to chain actions—launching a set of apps with one keyword, for instance.
If you only need the fastest-possible filename search, Everything remains the king. If you’re already deep into the PowerToys ecosystem, you might not miss Fluent Search’s extras. But for a Spotlight-caliber experience on Windows that you control—down to the indexing backend and plugin set—Fluent Search is worth a test drive.
What Comes Next
The project is under active development, with regular releases and an open issue tracker. Feature requests and bug fixes flow steadily, and the plugin catalog is expanding. The developer has shown commitment to reducing memory and install size, which bodes well for long-term viability. For now, the best approach is to install it, run it alongside your current tools for a week, and see if it earns a permanent hotkey on your keyboard.
