class | Lucene::NumericField

This class provides a Field that enables indexing of numeric values for efficient range filtering and sorting. The native types int32_t, int64_t and double are directly supported. However, any value that can be converted into these native types can also be indexed. For example, date/time values represented by a Date can be translated into a int64_t value. If you don't need millisecond precision, you can quantize the value, either by dividing the result or using the separate getters (for year, month, etc.) to construct an int32_t or int64_t value.
