Cloud & Hybrid Cloud Search

Search cloud repositories like Box and OneDrive alongside email, files, and SharePoint content, reaping the benefits of a single-pane-of-glass view for business content. Flexible indexing options (full local indexing of cloud content, partial local indexing, or no local index) allow IT administrators to control how users search cloud repositories.

Search on the Go

Take X1 desktop search with you on your mobile devices with X1 Search Mobile. Search your email, desktop files, and more directly from your mobile device. (Requires additional purchase). More on Mobile productivity  >

User-Centric Interface

A single, unified interface with fast-as-you- type search, 50+ refine columns, full fidelity preview of attachments and files, and a catalog of post-search actions retrieve and act upon results in the way a business professional recollects information.

X1 Search is built to empower business workers and enable productivity. Effective productivity search leverages the human brain to help people find what they know they are looking for. In the business world, this is what workers need daily – a tool to efficiently find the emails and office documents necessary to do their jobs.

X1 Search is specifically architected to retrieve results in the way a business professional remembers information. More often than not, professionals forget document names or where they filed a critical email, and spend countless hours sifting frustratingly inaccurate search results generated by a "relevance" algorithm. X1 simplifies search, retrieving results as fast as you type, anywhere in the email, file and SharePoint contents or metadata, empowering professionals to tactically sort through and act upon their information.

X1 can go beyond desktop search to offer enterprise search of other repositories with the X1 Rapid Discovery product. X1 Rapid Discovery is a proven eDiscovery and enterprise search solution that uniquely deploys within virtual environments to enable corporations, law firms and consultants to quickly identify, search, and collect distributed data wherever it resides in the cloud or within the enterprise.

Working in virtual desktop environment (VDI)? X1 Search is certified VMware Ready and there is a virtual edition of Search enabling a better VDI experience by providing users the comfortable interface and robust search engine of the X1 you know and love, with a back-end architecture optimized for virtual desktops.

X1 Search is the only solution flexible enough for a globalized workforce. Whether working on your office desktop, or logging onto a virtual desktop from a remote location, X1 Search takes the effort out of finding critical documents regardless of where you or your data reside.

Product Review

X1 Search


“If you can take advantage of X1 Search's ability to extend its reach to SharePoint or cloud-based email and Box or make use of its ability to build much more sophisticated search phrases than Lookeen can handle, X1 Search is the obvious choice. These additional capabilities - along with easier setup than Lookeen for some features and an equally easy-to-use interface - make it our Editors' Choice for desktop search utilities.”
