摘要: A classifier is used to predict relevant results with arbitrary filtering conditions specified by the user. The classifier model is stored as a database table and joined with a metadata properties table instead of calculating the query result probability using the full classifier model. A user-specified query based filter is applied to the joined tables to obtain the list of documents satisfying the filter. The probability is then computed using the sub-model.
摘要翻译: 分类器用于通过用户指定的任意过滤条件来预测相关结果。 分类器模型存储为数据库表,并与元数据属性表连接,而不是使用完整分类器模型计算查询结果概率。 用户指定的基于查询的过滤器应用于连接的表,以获取满足过滤器的文档列表。 然后使用子模型计算概率。

摘要: Optimized storage and query of multi-value properties is enabled by generating a base table for single value properties associated with a user-defined schema and a number of row-based tables for each different type of multi-value properties. By combining multi-value properties into row-based tables or even into compatible type tables, a number of tables to be created for a database system such as SQL system is reduced at the same time optimizing create/read/update/delete operations.
摘要翻译: 通过为每个不同类型的多值属性生成与用户定义模式相关联的单值属性的基表和多个基于行的表,可以实现多值属性的优化存储和查询。 通过将多值属性组合到基于行的表或甚至组合到兼容类型表中,为数据库系统(如SQL系统)创建的多个表将同时优化创建/读取/更新/删除操作。

摘要: Multiple search indexes can be served from a common set of resources. Instead of requiring a processor to be dedicated to serving a single search index, a processor can provide responsive documents for search queries that are based on different ranking algorithms and/or different sets of documents.
摘要翻译: 可以从一组共同的资源中提供多个搜索索引。 处理器不是要求处理器专用于提供单个搜索索引,而是可以为基于不同排序算法和/或不同文档集合的搜索查询提供响应文档。

摘要: To provide data from a database in response to an application query, the database is queried an initial time to provide a first set of data. For example, a “fast first page” may be requested, by requesting that all data which might appear on a first page to be displayed is obtained from the database first. After this, one or more subsequent asynchronous queries obtain the remaining information responsive to the query. Or, certain columns from the database (“spine columns”) may be requested in the initial query of the database, and the rest of the data requested subsequently. Thus, information needed to make an initial presentation to a user can be obtained first, and other information filled in subsequently.
摘要翻译: 为了响应于应用程序查询从数据库提供数据,查询数据库的初始时间以提供第一组数据。 例如,可以通过请求从数据库首先获得可能出现在要显示的第一页上的所有数据的“快速第一页”。 之后,一个或多个后续的异步查询响应于该查询获得剩余的信息。 或者,可以在数据库的初始查询中请求数据库中的某些列(“spine columns”),然后再请求其余的数据。 因此,可以首先获得对用户进行初始呈现所需的信息,以及随后填写的其他信息。
