QueryTermCount

计算查询词分词词组个数。

QueryTermCount create(OpsScorerInitParams params)

创建QueryTermCount对象。参数列表：params — scorer初始化参数，详情请参考OpsScorerInitParams手册。

QueryTermCount create(OpsScorerInitParams params, CString indexName)

创建QueryTermCount对象，只返回指定索引的term个数。参数列表：params — scorer初始化参数，详情请参考OpsScorerInitParams手册。indexName — 需要计算term个数的索引名称，必须为常量。

double evaluate(OpsScoreParams params)

计算查询词分词词组个数。参数列表：params — 算分输入参数，详情请参考OpsScoreParams手册。代码示例：

package users.scorer;
import com.aliyun.opensearch.cava.framework.OpsScoreParams;
import com.aliyun.opensearch.cava.framework.OpsScorerInitParams;
import com.aliyun.opensearch.cava.framework.OpsRequest;
import com.aliyun.opensearch.cava.framework.OpsDoc;
import com.aliyun.opensearch.cava.features.similarity.querymatch.QueryTermCount;

class BasicSimilarityScorer {
    QueryTermCount _f1;
    boolean init(OpsScorerInitParams params) {
        _f1 = QueryTermCount.create(params);
        return true;
    }

    double score(OpsScoreParams params) {
        OpsDoc doc = params.getDoc();
        float s1 = _f1.evaluate(params);
        doc.trace("s1 ", s1);
        return s1;
    }
};
