摘要： In one embodiment, a method includes receiving an update of activity associated with one or more content objects associated with a search term. The content objects associated with the search term are indexed on a list of one or more index servers or a term server. The list of the term server include identifier information of one or more content object types. The list of the index servers include identifier information of a single content object type. The method also includes determining whether the search term has a number of associated content objects exceeding a pre-determined threshold number; and modifying the list associated with the search term of a term server or one or more of the index servers based at least in part on the determination and in response to the update.

摘要： In one embodiment, a method includes receiving, from a user, a search query requesting objects of a first object type. The search query includes an inner query requesting objects of a second object type. The method includes identifying the objects of the second object type requested by the inner query using an inverted index of a second data store corresponding to the second object type; identifying, for each of the identified objects of the second object type, objects of the first object type using an inverted index of a first data store corresponding to the first object type; aggregating a plurality of search results responsive to the search query, each search result corresponding to an identified object of the first object type; and sending, to the user, one or more of the aggregated search results.

摘要： In one embodiment, a method includes determining rankings for a plurality of objects of a social-networking system, where the social-networking system includes a social graph that includes a plurality of nodes and a plurality of edges connecting the nodes. Each object corresponds to a node of the social graph, and each ranking for each object is determined based on a number of edges being connected to the node to which the respective object corresponds. The objects are stored in a plurality of partitions of a database, where each partition stores only objects having a particular ranking. The objects are indexed in the partitions by a plurality of search indices that each index only a particular one of the plurality of partitions.
