Thanks Dwane, I have a doubt, according to the java doc, the duplicates still continue to exist in the field. May be during query time, the field returns only unique values? Am I right with my assumption?
And also, what is the performance overhead for this UniqueFiled*Factory?

Is there a way to maintain distinct values for that field though I continue to add duplicate values through atomic update via solrj? Is there some property setting to have only unique values in a multi valued fields?
