This could be done with a function query, except that the function I would use does not exist. There is no function that returns the number of values that exist for a field. If there were, you could say:
-field:A OR (field:A and function() > 1) I don't know the Lucene data structures well, but I suspect this would be incredibly expensive to calculate.
