摘要
通过设计统一检索过程模型,并对统一检索的技术进行分析。采用PHP开发程序与Apache Web应用服务器相结合的方式,利用两者在字符运算处理速度的优异性和可靠性以及稳定性的特点,并采用性能优异的Web信息获取组件Client URLLibrary(CURL),来实现对科技文献网站的网页进行信息抓取,完成对不同异构数字资源的统一检索、统一显示和二次检索等功能。最后,对目前存在的问题提出了解决的思路。
By designing a process model of unification retrieval system,analyzing the technology of unification retrieval,combining the programming of PHP with Apache,and using outstanding Client URL Library（CURL）to acquire web pages and analysis,a unified search system was implemented.It intended to realize the following function such as retrieval in the different digital documentation databases,unification display and quadratic search.Finally,the paper presented solutions to current existing problems.
