Windows search has always been a bit of a gamble. Sometimes it finds what you need instantly; other times it feels like shouting into the void. OmniSearch changes that. After using it for a few weeks, I’ve stopped digging through folders, stopped opening Start search out of habit, and stopped wondering whether Windows will actually find the file I need. OmniSearch finally feels like the unified, reliable search bar Windows should have had years ago.
This open-source app is built for speed, using low-level NTFS indexing through the USN Journal and MFT to deliver near-instant search results across your drives. It offers a noticeably more responsive and capable search experience while staying fully local on your system.
For context, Everything (the other comparable free tool) remains the benchmark for pure filename search performance on Windows 11 (and older versions). OmniSearch is not positioned as a replacement for that level of raw speed, but instead takes a broader, workflow-focused direction.
The other main benefits of Omnisearch include:
- Cleaner UI
- Better inline previews
- Smarter autocomplete
- More consistent keyboard navigation
- No more “blank search results” moments
Alongside fast search, it combines tools that extend beyond simple lookup, including a quick-access window triggered by a global hotkey, file previews, duplicate detection, and built-in file actions, all wrapped in a clean and modern interface.
The result is a more complete experience. You're not just finding files faster, you're managing, reviewing, and organizing them without switching between multiple tools. And because it runs locally on your device, your file metadata stays private, with no data sent to external servers, though low-level indexing may require administrator privileges on some systems.
Search files and folders
At first, the interface can be a little intimidating because of all the options, but it's not intimidating at all.
First, at the top right, you can customize the indexing settings. If you plan to use OmniSearch to search everything on your computer, then you want to include all the drivers and folders.
If something isn't working correctly, you can always use the reindexing option.
In the Search tab, you can type your query, and results should appear almost immediately.
You can also use the filters to refine your search by extension, size, and date, and even by type (apps, media, docs, and archives). You can perform similar filtering on Windows Search, but the OmniSearch exposes the settings front and center.
From the search result, you can perform different actions, including open path, copy path, copy filename, copy full filename, rename, and delete.
You can even show previews without opening the file in a specific application using the "Show previews" option in the top-right, under the "Extension" section.
Compared to the built-in search engine, I was impressed with the nearly instant search experience once the tool had an index of all the files.
Search files using syntax
One powerful feature is the ability to perform inline searches using syntax. You see, by default, OmniSearch searches content using the data from the filename and metadata, but it doesn't search inside the file.
If you want the search to retrieve a file based on specific content, you'll have to use specific syntax. The caveat here is that searching inside files will take longer.
To search files based on their content, you need to use one of these syntax: content:, ansicontent:, utf8content:, utf16content:, and utf16becontent:, along with the context you want to find.
For example, type content:"Windows 11" and press "Enter." The tool will search the files and list results containing the keywords.
You can also use the extension filter to improve the search speed. For instance, report ext:txt content:"Windows 11" is faster than content:"Windows 11" by itself.
When using syntax, consider that content matching is case-sensitive. If the text has spaces, use quotation marks, and use one content clause per query. Finally, folders are not part of content search.
You can learn more about inline search in the "Syntax" tab available in the application, and on the official GitHub page for OmniSearch.
Find duplicate files
Perhaps one of the reasons to use this is the feature that allows you to find duplicate files on your computer.
You only need to open the "Duplicates" tab, set the minimum file size, and click the scan button.
The scan may take a while, but it'll find the duplicate files, which you can then compare and delete to free up space on your computer.
The only issue I found is that you can't be specific about the type of file or location you want to search for duplicates. The tool will search your entire computer for duplicate files.
Configuring OmniSearch
Although the default settings will suit most people, it's possible to configure some preferences. For instance, in the Settings tab, you can decide where OmniSearch runs in the background, you can enable the global shortcut, and it's even possible to remember the window size and position.
The tool offers an option to change the keyboard shortcut (Shift + Alt + S) and the number of results per page.
Theming for OmniSearch
Sure, you can change the light and dark color mode, but if you go to the Themes page, you can also change the scheme color using one of the nine different themes.
You only need to select the theme, and it'll apply automatically.
OmniSearch Download & Installation
The installation of the OmniSearch tool is straightforward. Once you download the latest version from the GitHub page, you'll have to launch the setup using the .msi or .exe file, and then continue with the typical next, next, next wizard.
After installation, you can launch the tool from the Start menu, and it'll also appear in the System Tray on the Taskbar.
You can also find a version in the Microsoft Store (listed below) for easier installation.
Note: The app is compiled for x64, but we did test it on an ARM laptop (ASUS Zenbook A16), and it ran just fine with no immediate issues or performance degradation.
Final thoughts
Overall, OmniSearch delivers a compelling alternative to the default Windows Search experience, especially for users who need speed and more control over how they interact with their files.
It doesn't try to outpace Everything in raw filename search performance, and that's the right approach. Instead, it focuses on what happens after you find a file. The combination of instant results, filters, previews, duplicate detection, and built-in actions creates a more complete workflow.
There is a slight learning curve at the beginning, particularly with the interface and advanced options like syntax-based searches. However, once everything is indexed and you get familiar with the layout, the experience becomes fast, predictable, and efficient.
Some other minor quibbles about Omnisearch could include:
- Some file types still rely on legacy indexing
- Needs better integration with Settings search
- Doesn’t yet unify app‑level search (Outlook, Teams, etc.)
Although Windows Search is enough for most people, the OmniSearch app offers a suitable alternative to file search on Windows 11.
If you're comfortable with Everything and only care about blazing-fast filename lookups, there may be little reason to switch. However, if you want a more modern, all-in-one solution that combines search with file management features, OmniSearch is absolutely worth adding to your setup.
