The "Performer" challenge

[Gdg]

Hello everybody.

I own a good collection of CD, ripped, converted to flac and stored into a QNAP NAS.
The QNAP runs a licensed instance of minimServer.

I'm mostly into jazz music and I patiently filled the "Performer" tag of each and every track of my library.
As editing front-end I used foobar2000.
The string was entered into the above tag like this:
"Ron Carter; Elvin Jones; Herbie Hancock"
(of course this is just an example...)
and Foobar200 splitted and stored that string inside the flac, like this:
. PERFORMER=Ron Carter
. PERFORMER=Elvin Jones
. PERFORMER=Herbie Hancock


As controller I mostly use these applications:
. JPLAY (on iPhone & iPad)
. Linn (on iPhone, iPad, android tablet)
. BubbleUpnp (android tablet)
. Foobar2000 (PC Windows, Iphone, Ipad, Android)

My wishes are:
1. to search by single "Performer" and find all albums s/he is playing in.
2. to play an album (or a track) and see the perfomers playing in it.


Now, I understand Perfomer is outside the basic group of tags searched/shown by the above apps.
Oh, yes, I can do a search by the Performer tag using the "smart browse" of MinimServer (wish 1: ok),
but I couldn't find a way to see what performers are playing a song (wish 2: KO).
My first Q:
Is there a way to instruct minimServer to show the content of the tag "Performer" of a track?
-
Anyway, I tried a work-around.

I've found out that cloning the content of the Performer tag into the Artist tag gets me exactly what I need.

But I don't want to phisically change the content of the Artist tag

So I tried this:
on the page <myminimserver>:9790/properties-advanced.html
. tagFormat: Artist.displayFormat={$Artist$Performer^^^;}

than, on the page <myminimserver>:9790/properties-server.html
. indexTags: All Artists:TrackArtist,Artist:AlbumArtist

Merging togheter Artist & Perfomer creates a "virtual Artist" tag that perfectly works when JPLAY searches inside its local db
I can search whatever artist I like (both main or side artist).
And I can see the whole band playing a song, since showing the "Artist" tag now means to show Artist+Perfomer.

Too bad, this doesn't work as expected with the "By folder" browse, since the sub-folder "TrackArtist" can't access the "virtual" Artist tag.

My 2nd Q:
. Is there a way to let minimServer to "smart browse" by the "virtual Artist" tag ?

Since I'm pretty sure I'm doing something wrong, please suggest me any solution you like to satisfy my needs.

Thank you very much.
