基于Oracle大数据的全文检索技术研究与实现

摘要

This article proposed a solution of full-text search technology based on huge amounts of oracle data by oracle components of Oracle Text and Ultra Search.It analyzed the better way to achieve the full-text search technology in the existing foreign affairs system,solved retrieval different data type (including LOB,etc.) through the same path and module and authority control brought by different middleware,greatly reduced the risk of a large amount of code modifications on the existing system,and improved the speed of index creation and search efficiency,provided users with a simple and convenient search method.%在Oralce组件Oracle Text和Ultra Search的基础上,提出了基于大数据的全文检索技术的一种解决方案.分析了在已有外事系统中实现全文检索功能较佳的一种方式,解决了对系统中不同格式数据(包括LOB等),通过统一路径进行检索的问题以及因不同中间件带来的用户模块和权限控制的问题,大为减少了大量的代码修改以及因修改代码对已有系统功能带来的风险,并且在较高程度上提高了索引创建速度以及检索速度,为用户提供了简单便捷的一种检索方式.
