Abstract: A specification of one or more query response modules from a third-party entity different from an entity providing a search service is received. A search query from a user is received. The search query is processed at least in part with the search service to determine whether any of the one or more query response modules are applicable to the search query. In response to a determination that at least one of the one or more query response modules is applicable to the search query, one of the query response modules is selected for the search query. The selected query response module is executed to determine a module answer content. The search query is processed to identify links to content responsive to the search query. A response to the search query is provided including by embedding the module answer content in a user interface providing at least a portion of the identified links.

Abstract: A client instance provides search suggestions based on a partial search query. The search suggestions include user search suggestions based on previous search queries performed by the user and instance search suggestions based on previous search queries performed on the instance. The client instance filters the instance search suggestions based on filter criteria associated with the user, such as an interface used by the user, a search context, user group that the user belongs to, domain used by the user, and so on. The client instance may remove the search suggestions that include blacklisted terms. The client instance may rank the search suggestions (e.g., based on frequency and/or recency) and enable the user to select those ranked search suggestions that meet or exceed a threshold.
