Can you access Siri search querys from an app that runs in the background? Lets say I install a app on my phone which runs in the background, now every time I open Siri and start with the word "BOX" as a example "box whatever" it will open a specfic website (like www.box.com) and use the words after box as a specific search query something like (www.box.com/search/whatever).

Essentially can a iOS app add functionality to Siri to redirect specific commands to the app which then builds a URL (or whatever it needs to do)?
No.
