It is easy to add indexing of any other field by adding the metadata field to indexTags , selecting Save and then select Restart so that MinimServer creates the additional indexes
For example if interested in Classical music SongKong adds the following metadata that would be useful to index:
So this would mean that the default profile indexTags field is set to
Artist, Date, Genre, All Artists, Composer, *RecentAdded, *RecentPlayed, #AudioData, #AudioFormat, Work,Orchestra,Conductor,Ensemble,Performer,Choir
If we we refresh our Control Point we now see these new indexes have been added.
