How to show specifc filters for specific groups

Question

Hi,
I have a sitecollection with lists A and B. There are two subsites.Each subsite has lists C and D.
Admin has access to everything.
Non Admins group(s) have access to specific subsite
I understand that search results are security trimmed with user group permissions.When Admin searches, he should be able to see results from all lists and he should also see filters A,B,C and D.
When non admin searches, he should be able see results only from specific subsites to which he has access and should be able to see the filters C and D.
How can I do this? The below approach I had involves creating lots of pages is there a better way.
I could create 4 pages at root sitecollection for 4 lists and add them to the SearchNavigation in SiteSettings with audience targetting.In each of those 4 pages, I can add SearchNavigation webpart with Search Results and Search box webpart and query transform
to fetch results for that specific list content type for that respective page.
At each subsite, I would have to add two pages with audience targetting in Search Navigation for lists C and D . In each of the two pages, I have to add the search Navigation webpart and results webpart which is query transformed for that specific list.
So in total I would require 8 pages ,4 for sitecollection and 2 each for 2 subsites.
How else can I achieve this?
One approach I had was to create a single result page at sitecollection level and add this url 4 times with different url parameter matching the list content type along with. audience targetting.This would ensure that, if Admin sees the page which has search
navigation webpart, he would see 4 links and others would see 2 links.
Similarly in subsite, I can add the two links to same result page along with two url parameters, 1) path( to that subsite) and 2)content type .
But is there a way where we can specify the contenttype and path in the url?
I tried results.aspx?contenttype=mycontenttypename&path="my url" but it does not work.
Is there any better way to achieve the same?

Unfortunately, it didn't work.  While I was able to add the second cover art, when the song from the album played it still showed the first album cover.  While the second album cover won't show unless I click the "part of a compilation" box in "cmd-i > Info".  This will work for the one song that I have checked.  Although I can select the songs in the album, whenever I attempt to assign the specific artwork to those songs for, the artwork applies itself to all the other songs on the cd.  Any other suggestions ?  All are greatly appreciated.  Thanks.
