文章基于前序研究所提出的饱和度和冗余度科学性评价指标和所构建的饱和文献数据集，对文献证据检索的饱和度和冗余度进行评价发现：单项检索时主题检索项效率最高；使用and连接组合项时应避免加入题名检索项；组合检索中“主题or题名or关键词or摘要”检索效率最高。

Based on the saturation and redundancy index issued by pre-research, this paper makes an empirical test on the literature retrieval under different retrieval methods. The results show that:  In single item retrieval, the efficiency of subject retrieval item is the highest; when using and to connect combined items, it should avoid adding Title retrieval item for retrieval, and the efficiency of subject and keyword in combined items is the highest; when using or to connect combined items, the efficiency of subject or title or keyword or summary is the highest. Based on the collaborative evaluation of saturation and redundancy, the retrieval efficiency of topic or title or keyword or abstract is the highest in combined retrieval.
