If you add multiple search tabs for the different search models, it
will try to find each ensemble in turn.  The correct way to try
multiple mutually-exclusive ensembles is to have a single search tab
for the set, and check each ensemble that should be considered.  (Or
is this what you did, and I misread?)  This will still only output the
best solution, I think.

I don't think this is possible with the main Phaser interface (or
command-line equivalent).  There is however a separate (very
experimental) app that I think will do what you want:

1) Open the Preferences, click "General", and check the box labeled
"Enable alpha-test programs and features"
2) Close and restart the GUI
3) Under molecular replacement, click the button "Parallel Phaser"
