iOS (Jailbreak): By default, Spotlight on iOS only searches for content on your device. If you want to expand that search, SLightEnhancerSearch adds all sorts of new search strings, including Cydia, Facebook, Google and lots more.
SLightEnhancer is built directly into Spotlight and works the same way Spotlight does. Once you set up the app and select the places you would like to appear in Spotlight, you can quickly search through a bunch of apps all from one place.
It works well and provides something similar to a universal search. You'll find SLightEnhancerSearch in Cydia. Check out AppAdvice's video above for a full breakdown of how it works.
