Advance ( int target ) : int	Advances to the first match beyond the current whose document number is greater than or equal to a given target. The implementation uses the skipTo() method on the subscorers.
DisjunctionSumScorer ( System subScorers ) : System	Construct a `DisjunctionScorer`, using one as the minimum number of matching subscorers.
DisjunctionSumScorer ( System subScorers, int minimumNrMatchers ) : System	Construct a `DisjunctionScorer`.
DocID ( ) : int
NextDoc ( ) : int
NrMatchers ( ) : int	Returns the number of subscorers matching the current document. Initially invalid, until Next() is called the first time.
Score ( Collector collector, int max, int firstDocID ) : bool	Expert: Collects matching documents in a range. Hook for optimization. Note that Next() must be called once before this method is called for the first time.
Score ( ) : float	Returns the score of the current document matching the query. Initially invalid, until Next() is called the first time.
Score ( Collector collector ) : void	Scores and collects all matching documents.

AdvanceAfterCurrent ( ) : bool	Advance all subscorers after the current document determined by the top of the `scorerDocQueue`. Repeat until at least the minimum number of subscorers match on the same document and all subscorers are after that document or are exhausted. On entry the `scorerDocQueue` has at least `minimumNrMatchers` available. At least the scorer with the minimum document number will be advanced.

InitScorerDocQueue ( ) : void	Called the first time next() or skipTo() is called to initialize `scorerDocQueue`.

The implementation uses the skipTo() method on the subscorers.

public Advance ( int target ) : int
target	int	The target document number. ///
