Comment 5 for bug 834910

The Banshee and Rhythmbox scopes of the music lens are set to return a maximum of 100 results if there's no search entered, 50 if there's a search term and 20 if it's a global search (i.e. from the home lens)

This was presumably done initially for reasons of performance and also due to the fact that it is difficult for the user to parse searches containing too many results. Few people will go through several hundred results rather than try to refine their search further.

There is an argument here for having the option for lenses to display "show more results" rather than "show X more results" as it is now, in situations where the number of results is artificially limited for performance or usability reasons.

The maximum number of results is set at http://bazaar.launchpad.net/~unity-team/unity-lens-music/trunk/view/head:/src/rhythmbox-scope.vala#L43 for Rhythmbox and http://bazaar.launchpad.net/~unity-team/unity-lens-music/trunk/view/head:/src/banshee-scope.vala#L47 for Banshee.
