Whether or not you use SpotLight Search in iOS 7, you might have a really good reason to start using it after installing a new jailbreak tweak called Search+
by iOS developer Ma Jun. Search+ will supercharge SpotLight Search with all new features that can make it more accessible and more useful.
Search+ makes SpotLight Search more accessible by working with Activator to let you access SpotLight Search from anywhere. You aren't limited to just the Home Screen anymore. You can assign an Activator action to Search+, and when you're on the Lock Screen or in an application, you can invoke that Activator action to bring up SpotLight Search and begin searching your iOS device for content:
It's worth mentioning that Search+ also forces SpotLight Search to support landscape orientation in addition to portrait orientation, so you will have access to SpotLight Search even in those applications that force you into landscape orientation.
Search+ also allows you to quickly text message/iMessage or call contacts by tapping and holding on contact search results until an Action Menu pops up. If you were to tap and hold on text message results that appears in the search results, a "Message" button will appear that will let you reply to that specific person that sent you that message. All messages are sent through the Messages application, just as all calls are sent through the Phone application.
Some additional features of the tweak include the very nice iOS 7-style blur that blurs out the application interface behind the SpotLight Search interface, as well as the ability to clear recent search history from SpotLight Search.
Search+ adds a preferences pane to the Settings application where you can configure many of the tweak's options to meet your needs:
From here, you can enable or disable the tweak on demand, choose your Activator or QuickDo activation method(s), enable or disable using Search+ on the Lock Screen, enable or disable folding sections by tapping on the headers, enable or disable tapping and holding on search results to display Action Menu buttons, and enable or disable clearing recent search results each time you close SpotLight Search.
Search+ is available in Cydia's BigBoss repository for 99¢, but it includes a 3-day fully-functional free trial that you can take advantage of before purchasing the tweak so you can see if it meets your needs. Search+ is only compatible with iOS 7, but runs on iPhone, iPod touch, and also iPad.
