This class should only be used if the other SortField /// types (SCORE, DOC, STRING, INT, FLOAT) do not provide an /// adequate sorting. It maintains an internal cache of values which /// could be quite large. The cache is an array of Comparable, /// one for each document in the index. There is a distinct /// Comparable for each unique term in the field - if /// some documents have the same term in the field, the cache /// array will have entries which reference the same Comparable. /// ///

For example, if the Terms contained integer values, this method
/// would return new Integer(termtext)
. Note that this
/// might not always be the most efficient implementation - for this
/// particular example, a better implementation might be to make a
/// ScoreDocLookupComparator that uses an internal lookup table of int.
///
termtext
that sorts according to the natural order of termtext
