Abstract: In one embodiment, a method includes receiving a search query to search for multimedia objects of the online social network; searching an index to identify multimedia objects based on the search query, wherein the index indexes multimedia objects and associated keywords, each keyword being extracted from communications associated with a respective multimedia object, wherein each communication is of a particular communication-type, and wherein each identified multimedia object is indexed with keywords matching at least a portion of the search query; calculating, for each identified multimedia object, an object-score based on a communication-type of a communication from which one or more of the matching keywords were sourced; and sending instructions for presenting a search-results page to a client system, the search-results page including references to identified multimedia objects having an object-score greater than a threshold object-score.

Abstract: In one embodiment, a method includes receiving a search query for multimedia objects of an online social network from a user of the online social network; searching an index of multimedia objects to identify multimedia objects indexed with keywords that match n-grams of the search query, the keywords having been extracted from reshares associated with the multimedia objects; calculating an object-score for each identified multimedia object based on social signals; generating search results with references to the identified multimedia objects that have an object-score greater than a threshold object-score; and sending to the user one or more of the search results as part of a search-results page.

Abstract: In one embodiment, a method includes A method comprising, by one or more computing devices of an online social network, receiving, from a client system of a first user of the online social network, a post that is parsed to identify a query, identifying one or more topics and one or more query-domains matching the query, searching an answers-index to identify one or more query-answer sets responsive to the query and matching at least one of the identified topics and at least one of the identified domains, searching, for each entity identified in each query-answer set, a posts-index to identify one or more comments corresponding to the identified entity, calculating a score for each comment based on social signals associated with the comment, and sending, to the client system of the first user, a suggested-answers page including references to each comment having a score greater than a threshold score.

Abstract: In one embodiment, a method includes receiving a search query. The method includes generating query commands based on the search query. The of query commands include a first query command comprising a query constraint for objects having a first privacy setting, and a second query command comprising a query constraint for objects having a second privacy setting, wherein the second privacy setting is more restrictive than the first privacy setting. The method includes searching to identify a first set of objects that match the first query command, and a second set of objects associated that match the second query command. The method includes generating one or more search results and sending a search-results page to the client system of the first user for display.
