function score modifier

of

static SearchScore of(Bson score)

Creates a SearchScore from a Bson in situations when there is no builder method that better satisfies your needs. This method cannot be used to validate the syntax.

Example
The following code creates two functionally equivalent SearchScores, though they may not be equal.

  SearchScore score1 = SearchScore.boost(
      SearchPath.fieldPath("fieldName"));
  SearchScore score2 = SearchScore.of(new Document("boost",
      new Document("path", SearchPath.fieldPath("fieldName").toValue())));
 

Parameters:

score - A Bson representing the required SearchScore.

Returns:

The requested SearchScore.
