新的function_score如何使用weight

[swallez]

According to Google translate: "How the new function_score uses weight", so I guess this is about documentation?

Please provide more context, as it's hard to understand what you have in mind with this very short sentence.

he might mean that,
java client write function ,just has weight and filter.

GET /_search
{
  "query": {
    "function_score": {
      "query": { "match_all": {} },
      "boost": "5", 
      "functions": [
        {
          "filter": { "match": { "test": "cat" } },
          "weight": 42
        }
      ]
    }
  }
}

FunctionScoreBuilders does not contain methods like weightScore.

public class FunctionScoreBuilders {
	private FunctionScoreBuilders() {
	}

	/**
	 * Creates a builder for the {@link DecayFunction exp} {@code FunctionScore}
	 * variant.
	 */
	public static DecayFunction.Builder exp() {
		return new DecayFunction.Builder();
	}

	/**
	 * Creates a builder for the {@link DecayFunction gauss} {@code FunctionScore}
	 * variant.
	 */
	public static DecayFunction.Builder gauss() {
		return new DecayFunction.Builder();
	}

	/**
	 * Creates a builder for the {@link DecayFunction linear} {@code FunctionScore}
	 * variant.
	 */
	public static DecayFunction.Builder linear() {
		return new DecayFunction.Builder();
	}

	/**
	 * Creates a builder for the {@link FieldValueFactorScoreFunction
	 * field_value_factor} {@code FunctionScore} variant.
	 */
	public static FieldValueFactorScoreFunction.Builder fieldValueFactor() {
		return new FieldValueFactorScoreFunction.Builder();
	}

	/**
	 * Creates a builder for the {@link RandomScoreFunction random_score}
	 * {@code FunctionScore} variant.
	 */
	public static RandomScoreFunction.Builder randomScore() {
		return new RandomScoreFunction.Builder();
	}

	/**
	 * Creates a builder for the {@link ScriptScoreFunction script_score}
	 * {@code FunctionScore} variant.
	 */
	public static ScriptScoreFunction.Builder scriptScore() {
		return new ScriptScoreFunction.Builder();
	}

}
