that are attached to their computers. With Leopard, Spotlight is able to search networked Macs running Leopard (both client and server versions) that have file sharing enabled. A feature called Quick Look has been added to the GUI that will display live previews of files within the search results, so applications do not have to be opened just to confirm that the user has found the right file. The syntax has also been extended to include support for worded boolean operators ("AND", "OR" and "NOT"). These variants of the operators are localized; while users that have their System language set to English may use an "AND", German users, for example, would have to use "UND". The character variants work with any system language. Also while Spotlight is not enabled on the server version of Tiger, it is on the server release of Leopard. In addition, where Spotlight in Tiger had a unique and separate window design, Spotlight in Leopard now shares windows with the Finder, allowing for a more unified GUI. The unique Spotlight window in Tiger allowed sorting and viewing of search results by any metadata handled by the Finder; whereas Spotlight Finder windows in Leopard are fixed to view and sort items by last opened date, filename and kind only. Under Leopard there is currently no way to save window preferences for the Finder window that is opened via Spotlight. Since Leopard the Spotlight menu has doubled as a calculator, with functionality very similar to the Google search feature (but without the need to be online), as well as a dictionary that allows one to look up the definition of an English word using the Oxford Dictionary included in macOS. Yosemite In OS X Yosemite, the Spotlight search UI was completely redesigned. Instead of it acting as a drop-down menu, it is now located in the center of the screen by default, though the search bar (and/or the window itself) can be dragged to wherever the user prefers it to pop up. In addition to doing everything that the previous versions of Spotlight could do, the Yosemite revamp of Spotlight adds a preview or info pane on the right side (with results on the left side), and also adds support for searching through Wikipedia, Maps, and other sources. iOS A search tool also named Spotlight has been included on iOS (formerly iPhone OS) products since iPhone OS 3.
