I have some BigDecimal values which should be indexed for searching. Lucene has NumericField but it has setters only for long, double, float and int. I could store it as a String but then I would not benefit from NumericRangeQuery.

How you have stored your BigDecimals? Any best practices to share?

Does Scala's BigDecimal violate the equals/hashCode contract?

as seen on Stack Overflow - Search for 'Stack Overflow'
As the Ordered trait demands, the equals method on Scala's BigDecimal class is consistent with the ordering. However, the hashcode is simply taken from the wrapped java.math.BigDecimal and is therefore inconsistent with equals. object DecTest { def main(args: Array[String]) { val d1 = BigDecimal("2") … >>> More
