布尔查询 meaning in English
boolean query
Examples
- Traditional search engines are based on information retrieval technologies . they implement operations such as boolean queries , proximity searches , text relevance and link analysis
自己简单翻译一下：传统的搜索引擎是基于信息检索技术。他们执行诸如布尔查询的操作，近似搜索，正文关联和连接分析。 - Storage subsystem serve as the storing system for index subsystem and query subsystem , in addition , it supply interfaces to xml application system . index subsystem is responsible to index xml documents in storage subsystem and includes content index and structure index
索引系统主要为查询系统服务，为查询系统实现全文查询、布尔查询、路径查询提供支撑；索引系统还提供一些接口，使得外部程序可以不经过查询系统也能访问索引系统。 - Having studied the overall framework of the existent search engine system , we adopted the idea of trade - off algorithm to process the three - level index structure of chinese character for the implementation of chinese boolean operation , according to the different expression between chinese and english . this can greatly enhance the speed and veracity of chinese query
通过对源代码的分析,我们在保持原搜索引擎总体设计不变的情况下,在原有功能基础上,针对中英文信息表达的区别,对中文汉字的三级索引结构采用折衷处理的算法思想来实现中文布尔查询功能,以提高中文查询的检索速度和准确性。
