摘　　要：在中文全文检索系统中引入了混合索引,建立了混合索引之Hash索引,给出了Hash索引在内存中的存储结构,并给出了这种索引下的检索算法。这种索引既能保证索引的全面性,又能提高系统检索效率。通过实际构建系统,探讨了基于混合索引的中文全文检索系统的实现。The authors introduce mixed indexing into Chinese full-text retrieval system, establish Hash indexing in mixed indexing, provide a storage structure of Hash indexing in memory, and provide a retrieval algorithm in such kind of indexing. This indexing can not only ensure the comprehensiveness of the indexes, but also enhance the efficiency of system retrieval. By actual examples, the authors discuss the realization of a Chinese full-text retrieval system based on mixed indexing. 3 figs. 4 tabs. 5 refs.
