Answer 1

正如注释中所述，当您使用Lucene4.x时，您使用的是为Lucene3.x编写的代码。NumberTools在4.0中被删除（从2.9开始，可能更早）。

对于数字字段，您应该使用适当的字段类型，而不是自己进行任何花哨的转换。例如，longfield或intfield。

如果您确实必须自己转换值，Numericutils将替换旧的NumberTools的功能。所以不是：

string s = NumberTools.longToString(longval);
//index the string...

BytesRef longvalRef = new BytesRef();
NumericUtils.longToPrefixCoded(longval, 0, longvalRef);
//index the BytesRef...

不过，实际上应该使用longfield。请参见关于Numericutils的说明：

注意：此API仅用于内部目的，在下一个版本中可能会以不兼容的方式进行更改。

例如，在4.0和4.10中，它肯定有。
