// in future, it would be good to simplify this to always work with a bag
// (converting all sets to bags) until the end when we enforce distinct
// The number returned indicates the occurence of the data in the SelectResults
// Thus if the SelectResults is of type ResultsSet or StructSet
// then 1 will indicate that data was added to the results & that was the
// first occurence. For this 0 will indicate that the data was not added
// because it was a duplicate
// If the SelectResults is an instance ResultsBag or StructsBag , the number will
// indicate the occurence. Thus 1 will indicate it being added for first time
// Currently orderBy is present only for StructSet & ResultSet which are
// unique object holders. So the occurence for them can be either 0 or 1 only
