Windows Search has always been a gamble. Sometimes it finds what you need instantly; other times it’s like screaming into the void. Omnisearch change that. After using it for a few weeks, I stopped searching folders, I stopped opening Start Search out of habit, and I stopped wondering if Windows will really find the file I need. OmniSearch finally feels like the unified, reliable search bar that Windows should have had years ago.
This open source application is designed for speed and uses low-level NTFS indexing through USN Journal and MFT to deliver near-instant search results on your drives. It offers a noticeably more responsive and capable search experience while remaining completely local to your system.
For context, All (the other comparable free tool) remains the benchmark for pure file name search performance in Windows 11 (and earlier). OmniSearch doesn’t position itself as a replacement for that level of raw speed, but rather takes a broader, workflow-focused direction.

The other main benefits of Omnisearch include:
- Cleaner user interface
- Better online previews
- Smarter autocomplete
- More consistent keyboard navigation
- No more “blank search results” moments
In addition to quick search, it combines tools that go beyond simple search, including a quick access window activated by a global hotkey, file previews, duplicate detection, and built-in file actions, all in a clean, modern interface.
The result is a more complete experience. Not only will you find files faster, you’ll manage, review, and organize them without having to switch between multiple tools. And because it runs locally on your device, your file metadata remains private and no data is sent to external servers, although 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 is not at all.
First, at the top right, you can customize your indexing settings. If you plan to use OmniSearch to search everything on your computer, then you’ll want to include all drivers and folders.
If something is not working correctly, you can always use the reindex option.
In the Search tab, you can type your query and the results should appear almost immediately.
You can also use filters to refine your search by extension, size and date, and even by type (applications, media, documents and files). You can do similar filtering in Windows Search, but OmniSearch exposes the settings front and center.
From the search result, you can perform different actions, including open path, copy path, copy file name, copy full file name, rename, and delete.
You can even show previews without opening the file in a specific application using the “Show previews” option at the top right, in the “Extension” section.
Compared to the built-in search engine, I was impressed with the almost instant search experience once the tool had an index of all the files.
Find files using syntax
A powerful feature is the ability to perform online searches using syntax. You see, by default, OmniSearch searches for content using file name data and metadata, but it does not search within the file.
If you want the search to retrieve a file based on specific content, you must use a specific syntax. The caveat here is that searching within the files will take longer.
To search for files based on their contents, you must use one of these syntaxes: content:, anxious:, utf8 content:, utf16 content:and utf16becontent:along with the context you want to find.
For example, write content:”Windows 11″ and press “Get into.” The tool will search the files and list the results that contain the keywords.
You can also use the extension filter to improve search speed. For example, report ext: text content: “Windows 11” is faster than content:”Windows 11″ by himself.
When using the syntax, keep in mind that content matching is case-sensitive. If the text has spaces, use quotes and use one content clause per query. Finally, folders are not part of content search.
You can get more information about online search in the “Syntax” tab available in the application and in 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 just need to open the “Duplicates” tab, set the minimum file size and click the scan button.
The scan may take a while, but it will find the duplicate files, which you can then compare and delete to free up space on your computer.
The only problem I found is that you can’t be specific about the file type or location you want to search for duplicates. The tool will search your entire computer for duplicate files.
OmniSearch Settings
Although the default settings will suit most people, it is possible to configure some preferences. For example, in the Settings tab, you can decide where OmniSearch runs in the background, you can enable the global shortcut, and it is even possible to remember the size and position of the window.
The tool offers an option to change the keyboard shortcut (Shift + Alt + S) and the number of results per page.
Themes 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 color scheme using one of nine different themes.
You just need to select the theme and it will be applied automatically.
Download and install OmniSearch
Installing the OmniSearch tool is easy. Once you download the latest version from the GitHub pageyou will have to start the installation 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 menuand it will 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 tested it on a ARM laptop (ASUS Zenbook A16), and it worked fine with no immediate issues or performance degradation.
Final thoughts
Overall, OmniSearch offers 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 outperform Everything in raw file name lookup performance, and that’s the right approach. Instead, it focuses on what happens after a file is found. 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 first, particularly with the interface and advanced options like syntax-based searches. However, once everything is indexed and you become familiar with the layout, the experience becomes fast, predictable, and efficient.
Some other minor quibbles about Omnisearch might include:
- Some file types still rely on legacy indexing
- Need better integration with configuration search
- It still does not unify search at the application level (Outlook, Teams, etc.)
Although Windows Search is sufficient for most people, the OmniSearch app offers a suitable alternative to searching for files in Windows 11.
If you’re comfortable with Everything and only care about lightning-fast file name 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 worth adding to your setup.
