Spotlight feels more mature and efficient with Leopard. Small new features will improve the experience of using Spotlight. For example, web sites you visit are automatically indexed by Spotlight, allowing you to retrieve pages you visited recently based on their contents, right from Spotlight menu! Spotlight is now a great application launcher, for when you enter a few letters from an application name, this application will be selected among results, and you can launch it by simply pressing the Return key. And if the application doesn’t come up at the top of the list after you typed a few letters from its name, select it and next time it will appear on top automatically. Here is a quick look on these improvements.
Spotlight now works in concert with Calculator and Dictionary to provide calculation results as well as word definition right within its menu. A nice touch!
A welcomed improvement is the ability to easily filter results only based on file name, with the click of a button. This is also possible from Spotlight menu by adding the keyword
name: before your query. For example, type
name:"file name" in order to match files with “file name” in their names.
