摘　　要：为了满足用户对桌面搜索引擎准确、快速、易用的迫切要求,将通用搜索技术、垂直搜索技术中"先建立索引再进行搜索"的搜索机制和若干功能借鉴到桌面搜索技术,设计并实现了桌面搜索引擎FileFinder。功能测试验证了该软件不仅实现了关键字搜索、文件类型搜索等常用功能,而且具有结果匹配度排序、在搜索结果中再次搜索、以文件附加属性进行搜索等其他桌面搜索引擎不具备而用户需要的功能。对比测试结果既体现了FileFinder在搜索速度上与Windows桌面搜索引擎相比的优势,也表明在不实现全文检索功能的前提下,FileFinder建立索引的时间仅约为Google桌面搜索引擎的一半。To meet users＇ urgent requirements of accuracy, rapidity and usability to desktop engines, desktop search engine FileFinder is designed and developed, which combined the search mechanism of searching-after-indexing and several functions in general search technology and vertical search technology with desktop search technology. Function tests validate that besides the commonly-used search functions, such as key word search, file type search, some functions necessary to users but lack in other desktop engines are also included in FileFinder, such as results sorting according to matching degree, second time search in the search results, and search according to the file additional attributes. Contrast test results not only demonstrated its search speed advantage over Windows desktop search engine, but also showed that leaving out the full-text search function, FileFinder needs only approximate half time to establish index compared with Google desktop search engine.
