Abstract: In one embodiment, a method includes receiving a first search query including a selection of a first query-domain. The first query-domain may correspond to a first object-type. The method includes identifying a first set of objects of the plurality of objects matching the first object-type. The method includes sending a first search-results interface responsive to the first search query. The first search-results interface may include references to one or more of the identified objects from the first set of objects and one or more query-filter elements. Each query-filter element may correspond to a query-filter associated with the first query-domain. Each query-filter element may be activatable to apply the associated query-filter to the identified objects. The method includes receiving a second search query including a selection of one or more of the query-filters in response to the first user activating the corresponding query-filter elements.

Abstract: Systems, methods, and non-transitory computer-readable media can determine that a first content item was provided for publication through the social networking system. At least some portions of the first content item that match content included in a second content item are determined, the second content item being accessible through the social networking system. A determination is made that the portions of the first content item include at least some copyrighted content from the second content item. At least one notification is provided to a publisher of the second content item, wherein the notification indicates a potential copyright violation by a publisher of the first content item, and wherein the notification identifies at least some portions of the first content item that match copyrighted content in the second content item.
