Class DateField

java.lang.Object
  fr.gouv.culture.sdx.search.lucene.DateField

public class DateField
extends java.lang.Object

Same code as org.apache.lucene.document.DateField but with changes to handle pre-1970 dates. Provides support for converting dates to strings and vice-versa. The strings are structured so that lexicographic sorting orders by date. This makes them suitable for use as field values and search terms.

Note: dates before 1970 CAN be used, and therefore CAN be indexed.
