Hi, This is still possible (in reality it was broken in Lucene version prior 4.0 if you refer to Document.setBoost() -> see changelog/MIGRATE.txt): You have to add an additional DocValues field (a long or double numeric) and use a FunctionQuery / CustomScoreQuery to modify the score based on this value.
