This paper presents a methodology for retrieving sailing guides from a web-based sailing direction database. The basic idea is to build and utilize an index table, which relates the keywords extracted from the sailing direction to the URL's of the relevant pages. The topics covered in this paper spread from the basics about database design such as data modelling to the considerations for the search engine of the retrieval system. The major issues discussed include : 1. how to utilize the existing HTML framework with no modification ; 2. how to simplify and automate the procedures for data recording and updating ; and 3. how to design the search engine so that the fast and accurate retrieval of relevant pages could be achieved. Our experimental results show that with the use of the index table, the retrieval time has been considerably shortened.
