Hi "sc", I suspect you are hitting OOM for makeDistanceValueSource call on RecursivePrefixTreeStrategy. That strategy is best for filtering (the query), but it's a memory pig for distance sorting requirements. Instead, use PointVectorStrategy for the makeDistanceValueSource purpose. For that strategy, you only need it to do just that, so you can enable docValues and disable the "index". That strategy accepts a FieldType in the constructor. PointVectorStrategy is limited to one point per document per field, and always uses double precision on both "x" and "y". ~ David
