Support for server search querie

Feature description:

I want an button or an automatic event that is capable of searching with the subsonic search API.
This is required for some Software especially for Octo-Fiesta that works as an Proxy so that you can stream and download contet that is not available an the subsonic server (GitHub - V1ck3s/octo-fiesta: A Subsonic API proxy server that transparently integrates Deezer as a music source.). I think this will be a major change in selfhosting music.

Problem solved:

It solves the problem that music is only searched locally and not with the API

Brought benefits:

I can use symfonium solo again. At the moment I use Tempus or Musly to stream content I dont have and make playlists but Symfonium has more features and better Styling so for example when driving I use symfonium thats 2-3 apps for something I can use 1

Other application solutions:

 
Tempus, Musly, every other client I know of searches with the API
