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.”
