Abstract: A search term used in an online search is analyzed to determine a concept corresponding to the search term, the concept being present in an ontology related to a subject-matter domain of the search term. A set of concepts is selected from the ontology, including a related concept related to the concept in the organization of the ontology. A set of subscriber data sources is determined where a subscriber data source in the set subscribes to a concept in the set of concepts. From the set of subscriber data sources, a subset of those subscriber data sources is identified whose data is not participating in a result set corresponding to the search term. A non-participation message is sent to a subscriber data source in the subset of subscriber data sources.

Abstract: For online searching, data of a user activity is analyzed where the user activity occurs at an application other than a search application and the search application is used for the online searching. In response to the analyzing, a topic of interest of the user is identified. A search term input is detected at the search application. A subject of the search term is identified. The search term is modified using a modifier. The modifier is a term related to the topic of interest, and the online searching occurs in response to the modified search term.
