>In addition to degragmentation, you should also consider re-ordering the table to its "natural" order. For example, if you have a table that's ordered by one particular field, re-building that table so that the records are in that order can yield a reduction of index size of up to 20%.

How would this affect the case - the usual case, I believe - where there are several indices, on differente fields or expressions?
