There is: Numerics does not have a backing dictionary. Instead of storing the values via the intermediate ordinals-map (aka by reference), they are stored directly. Overall it takes up less space and makes a lot of things easier (and a few things harder, as you have found out). > How do I get to the ordinal for number and date fields? You don't really. You will have to assign ordinals yourself by sorting all the existing values upon first call. > I assume my fallback is to not index with doc values, and use an uninverting > reader to get the field data. Is there a better approach? You could index your integers as DocValued Strings, prefixed with zeroes to ensure same length and proper integer sort. - Toke Eskildsen
