Class MatchScorer (2.0.0)

public class MatchScorer

Assigns a document score based on frequency of terms in TextFields and HTMLFields.

If you add a MatchScorer to a SortOptions as in the following code:

  SortOptions sortOptions = SortOptions.newBuilder()
      .setMatchScorer(MatchScorer.newBuilder())
      .build();
 

then this will sort the documents in descending score order. The scores will be positive. If you want to sort in ascending order, then use the following code:

   SortOptions sortOptions = SortOptions.newBuilder()
       .setMatchScorer(MatchScorer.newBuilder())
       .addSortExpression(
           SortExpression.newBuilder()
               .setExpression(SortExpression.SCORE_FIELD_NAME)
               .setDirection(SortExpression.SortDirection.ASCENDING)
               .setDefaultValueNumeric(0.0))
       .build();
 

In this example, the score will be negative.
