Rig Manager search string syntax?

  • Just installed Rig Manager and loving the preview feature for easy access to the rig exchange.
    Looking forward to many 'lost' evenings exploring the 5000+ community rigs.
    My only minor grumble is the very basic search options, but maybe I am missing something.
    Has any one found some search string syntax that allows options above a single text string?, e.g. "Marshall -JTM" for all rigs with the word Marshall but without the word JTM.
    Any way to only search in amp names?
    Nothing in the manual and nothing I have tried has worked.
