Cloud & Hybrid Cloud Search

Search cloud repositories like Box 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.

Federated Search

X1 unifies search results across desktops, network file shares, email, cloud sources (e.g. Box, AWS), and more, enabling you to preview and act upon information no matter where it lives.

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.
