Naval vessel is a huge system, which has a wide variety, a large number of devices.With the rapid development of naval vessels technology, more and more equipment which has complex structure are applied to warships. On the one hand, equipment has some technical documents with a great volume of data and multiple formats. Therefore, how to manage these technical data and to get the useful information quickly is a problem to be solved currently. On the other hand, the complex structure of equipment causes warship maintenance become inconvenient. How to respond to breakdown quickly and effectively and to help maintenance staff make maintenance plan is one of important problem to be solved.According to actual demand, it has an intensive study and design about warship maintenance and support system and integrate the application of the full-text retrieval technology to solve the above problems in the article.In this paper, warship maintenance and support system is the foundation to solve related problems, First of all, according to the development process of software engineering and combining with the user's requirement, this paper did the requirements analysis on warship maintenance support system, then make the overall design and detail design of system.And finally, Completing the basic function of the system through the code and test.It adopted the technology of full-text retrieval to solve the problems about rapid location of technical data and fast response of breakdown in the warship maintenance support system. Chinese word segmentation is an important part of the full-text retrieve, and it is also a limit factor of full-text retrieve. So this article introduces the relevant technology of the Chinese word segmentation and word segmentation algorithm. and emphatically introduces several kinds of Chinese word segmentation dictionary mechanism, word segmentation mechanism of mine named double hash encode segmentation dictionary mechanism was proposed based on above dictionary mechanism. The experimental results show that the word segmentation mechanism we provided has improved the efficiency of Chinese word segmentation.In order to improve the reliability of the system, increase the throughput and provide query speed, this paper adopted the cloud retrieval technology to realize it.This paper has done the following job.First, realizing the function of warship maintenance support system related. The second one is studying Chinese word segmentation dictionary mechanism and improving them, this paper proposes a new Chinese word segmentation dictionary mechanism.The third one is researching related technology ofSolrCloud, and applied cloud retrieval to improve the efficiency of full-text retrieval in the system.
