| Provides support for converting dates to strings and vice-versa.
The strings are structured so that lexicographic sorting orders by date,
which makes them suitable for use as field values and search terms.
Note that this class saves dates with millisecond granularity,
which is bad for
RangeQuery and
PrefixQuery , as those
queries are expanded to a BooleanQuery with a potentially large number
of terms when searching. Thus you might want to use
DateTools instead.
Note: dates before 1970 cannot be used, and therefore cannot be
indexed when using this class. See
DateTools for an
alternative without such a limitation.
