DateTools
instead. This class is included for use with existing
indices and will be removed in a future release.public class DateField extends Object
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.
