    • Techniques for filtering a full-text search result in a full-text search engine level are described herein. According to one embodiment, a filter is defined via a definition statement a filter using a filter name which identifies a filter object representing an implementation of the filter. In response to a search query received at the ORM system from an application client, where the search query identifying the filter via the filter name, a full-text search engine is invoked to perform a full-text search in a database based on one or more keywords in the search query. The filter object is identified based on the filter name extracted from the search query and the filter object associated with the search query is invoked using the filter name of the filter object to filter a search result generated from the full-text search engine. Other methods and apparatuses are also described.
    • 本文描述了用于在全文搜索引擎级别过滤全文搜索结果的技术。 根据一个实施例,通过定义语句定义过滤器,该过滤器使用过滤器名称来标识表示过滤器的实现的过滤器对象。 响应于来自应用客户端在ORM系统接收的搜索查询,其中通过过滤器名称识别过滤器的搜索查询,调用全文搜索引擎以基于一个或多个文档搜索在数据库中执行全文搜索 搜索查询中的更多关键字。 基于从搜索查询提取的过滤器名称来识别过滤器对象,并且使用过滤器对象的过滤器名称来调用与搜索查询相关联的过滤器对象,以过滤从全文本搜索引擎生成的搜索结果。 还描述了其它方法和装置。

    • Techniques of index clustering for full text search engines are described herein. In one embodiment, a full text search is performed by a search node using a local copy of an index within the searching node during a search session. In response to an update of a list of data entries the relational database through a Common API (common in the sense the update triggered to the relational DB will also trigger an index change), an index update event is scheduled to update a master copy of the index directory. Periodically the local copy of the index directory is updated by copying index data from the master copy of the index directory (totally or incrementally). Other methods and apparatuses are also described.
    • 本文描述了全文搜索引擎的索引聚类技术。 在一个实施例中,搜索节点在搜索会话期间使用搜索节点内的索引的本地副本来执行全文搜索。 为了响应数据条目列表的更新,关系数据库通过Common API(通常在触发到关系数据库的更新意义上也将触发索引更改),索引更新事件被调度为更新主 索引目录。 通过从索引目录的主副本(完全或递增地)复制索引数据来定期更新索引目录的本地副本。 还描述了其它方法和装置。
