Methods, systems, and apparatus include computer programs encoded on a computer-readable storage medium, including a system for providing content. A stored query and a set of features of the stored query are accessed. The set of features of the stored query specifies a main query topic and at least one query subtopic. A hierarchical application classification for a particular application is accessed that specifies at least a main application category and an application sub-category for the particular application. A level of similarity is determined between the set of features of the stored query and the hierarchical application classification. A determination is made that the particular application is relevant to the stored query based on the level of similarity meeting a specified threshold. The stored query is indexed as a query that triggers presentation of information related to the particular application when the stored query is received.
