C# Class Lucene.Net.Search.DisjunctionMaxScorer

The Scorer for DisjunctionMaxQuery's. The union of all documents generated by the the subquery scorers is generated in document number order. The score for each document is the maximum of the scores computed by the subquery scorers that generate that document, plus tieBreakerMultiplier times the sum of the scores for the other subqueries that generate the document.
