Keyword search has been recently extended to relational databases to retrieve information from text-rich attributes. However, all the existing methods focus on finding individual tuples matching a set of query keywords from one table or the join of multiple tables. In this project, we will systematically investigate a novel theme of aggregate keyword search: finding minimal group-bys covering a set of query keywords well, which is useful in many applications.

关键字搜索最近已经扩展到关系数据库，以从文本丰富的属性中检索信息。然而，所有现有的方法都集中在从一个表或多个表的连接中找到与一组查询关键字匹配的单个元组。在这个项目中，我们将系统地研究聚合关键字搜索的一个新主题：找到覆盖一组查询关键字的最小分组，这在许多应用中是有用的。
