public class MatchScorer
extends java.lang.Object
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.| Modifier and Type | Class and Description |
