LUCENE-446 allows also score manipulation. It can also be used to filter docs by assigning 0 score to out-of-range docs. But note two aspects of using search.function: (1) values cannot exceed Integer.MAX_VALUE. (some examples given here had larger values...) (2) all values are loaded (once, cached) into memory, so expect RAM usage of numDocs * 1/2/4/8 bytes, depending on the maximal needed value.
