Fire TV remote control voice input?

For example, when I watch my amazon fire TV. Amazon music open and go into the search bar and speak into the remote control, the fire TV stick jumps back to the start page and searches under general. But then I would like to search specifically for Amazon music or netflix. Does anyone know if this is a matter of attitude?

The search command should be restricted as follows: "Search… To…"

E.g. "Search Peter Alexander on Amazon Music"
