The request is to be able to modify the unique capability to return documents that are truely unique within the context of the results. This means that only those unique results that actually only existed once in the non-uniquified result set are returned. I am thinking that this can be extended to specify a max-count on the unique results such that those unique results that only occured up to the specfied max-count are actually returned.

Perhaps #MAX_UNIQUE_COUNT(1) && #UNIQUE(FIELD1,FIELD2)

Add MAX_UNIQUE_COUNT functionality
cf3852b 
Add the ability to specify a max count on results from the unique
operation such that only the unique results that occurred up to the
specified max count are returned.

This max count can be specified either via the function
MAX_UNIQUE_COUNT or via the query parameter max.unique.count.
