摘要： A method, system and program storage device are provided for extending an inverted index, which comprises first and second inverted index subfiles to increase the speed of establishing and updating inverted index files. The method includes performing ordered keyword indexing operations of generating an inverted index from data sources, in which a frequency of occurrence of keywords in each of the data sources is calculated, and writing each keyword, the data sources, and the frequency of occurrence of each keyword in the corresponding data sources to the inverted index. If a number of data sources involved in the indexing operations reaches a first threshold, then writing contents of the inverted index as a smallest grid into the first inverted index subfile. If a number of smallest grids in the first inverted index subfile reaches a second threshold, then merging the smallest grids into a merged grid and writing the merged grid into the second inverted index subfile. If the number of merged grids in the second inverted index subfile reaches a third threshold, then further merging the merged grids into a larger merged grid, and writing the larger merged grid back into the first inverted index subfile.

摘要： The present invention provides a search ranking method suitable for a file system, including receiving a query, calculating final relevance scores of individual file items with respect to the query at least partially in accordance with energy scores of individual nodes on a current file system energy tree, and outputting a list of search results based on the final relevance scores. The file system energy tree is updated in response to an operation on the file system performed by a user, wherein the file system energy tree has a tree structure corresponding to that of the file system, and the individual nodes thereof respectively corresponds to the individual file items in the file system
摘要翻译：本发明提供一种适用于文件系统的搜索排序方法，包括接收查询，至少部分地根据当前文件系统能量树上各个节点的能量分数来计算关于查询的各个文件的最终相关性分数并且基于最终相关性得分输出搜索结果的列表。响应于由用户执行的对文件系统的操作来更新文件系统能量树，其中文件系统能量树具有与文件系统的树结构对应的树结构，并且其各个节点分别对应于单个文件文件系统中的项目

摘要： The present invention provides a search ranking method suitable for a file system, comprising: receiving a query; calculating final relevance scores of individual file items with respect to the query at least partially in accordance with energy scores of individual nodes on a current file system energy tree, and outputting a list of search results based on the final relevance scores; and updating the file system energy tree in response to an operation on the file system performed by a user, wherein the file system energy tree has a tree structure corresponding to that of the file system, and the individual nodes thereof respectively corresponds to the individual file items in the file system. The present invention also provides a corresponding file system search engine and computer program product. With the present invention, files and file folders that the user is interested in are usually arranged in relatively higher positions of the list of search results in file system search. Moreover, with the increase in the user's clicks on the file, the list of search results can be dynamically adapted to changes in the user's interest or preference.

摘要： The present invention is directed to a method and apparatus for establishing documents relationship based on user's operation upon search result. When a user uses search engine to search for documents with a query in repository, the search result may be a list of ranked documents, and these documents may contain a lot of relationship in term of the specific query. If the user clicks some search result further, and if the click and open operation meet certain conditions, for example exceed a period of time, the clicked document could be deemed as related to the search query. Furthermore it could be inferred that there is a strong relationship between different documents clicked by the user. The present invention records the relationship between documents and presents it to the user when necessary.
