In this paper, we propose RIST, a novel index structure for searching XML documents.
提出了一种用于搜索XML文档的新的索引方法即RIST。
Our experiments show that RIST is effective and efficient in supporting structural queries.
实验表明RIST在支持结构查询上是一种高效的方法。
Furthermore, RIST provides a unified index on both content and structure of the XML documents, hence it has a performance advantage over methods indexing either content or structure.
另外，RIST还在XML文档的内容和结构上提供了一个统一的索引，所以它的一个很明显的优势就是克服了仅仅根据内容或结构建立索引的弊端。
