Is your feature request related to a problem? Please describe.

Yes, compared to the server app, when I use the search bar inside the app, the search does not extend to other deck boards like it does in the server app.

Describe the solution you'd like

I would love to see the app display search results like it does on the server app: also show other deck boards results.

Describe alternatives you've considered

Try to remember in which deck board the target card was, then search again inside the correct board.
