一个带有Cache的检索系统的设计与性能研究

A Cached Information Retrieval System and the Performance Analysis

为了对短信息进行高效地检索，设计了一个Ｃ／Ｓ检索系统，实现对英文和日语片假名的高效混合检索。通过分析缓冲区配置参数对数据载入的影响，给出了衡量缓冲区规模合理性的指标。

For the short text retrieval,the traditional,such as the relational data base and the full-text search,are not effcient.In this paper we designed a client/server system to achieve the high performance of the short text searching.At the end of the paper,we measured the performance of the system and compared it with that of the system which using the standard I/O.And a variable,buffer-update- rate,is defined to indicate the rationality of the buffer size.
