Separate bit slicing and String encoding.... they are independent. If a,b,c,d are prefix codes designating precision, and w,x,y,z are each 2 bits of the number, then ax bxy cxyz dxyzw Everything after the prefix can be encoded in a single character in each case. Lucene's prefix encoding of the index will remove some of the redundancy... buy only for numbers that are very packed together. -Yonik --------------------------------------------------------------------- To unsubscribe, e-mail: java-dev-unsubscr...@lucene.apache.org For additional commands, e-mail: java-dev-h...@lucene.apache.org
