Play Doctor is cool, but not really what I'm thinking of here. Play Doctor includes results that aren't literally in the search parameters. And the results also can't be channeled into a playlist or view.
I guess the crux of what I'm asking is to be able to create a filter that acts like 'Search' and returns any tag with that value. So something like:
[Search] = "Peter Gabriel"
would return any media with "Peter Gabriel" in any field. Once that exists it could be used in any playlist or view and combined with other filters if needed. Right now I have:
([Artist]="Peter Gabriel" or [Album Artist (auto)]="Peter Gabriel" or [Band]="Peter Gabriel" or [Musicians]="Peter Gabriel" or [Featuring]="Peter Gabriel" or [Actors]="Peter Gabriel" or [Author]="Peter Gabriel" or [Director]="Peter Gabriel" or [Lyricist]="Peter Gabriel" or [Composer]="Peter Gabriel" or [Conductor]="Peter Gabriel" or [Soloists]="Peter Gabriel") ~sort=[Rating]-d,[Album],[Media Type],[Album Artist (auto)],[Disc #],[Track #],[Name]
and this only encompasses the fields I can imagine. His name might appear in a custom field and that wouldn't appear in this list. Also, it's extremely unwieldy to create this filter.
