Abstract: Indexing and retrieving real time content in a social networking system is disclosed. A user-term index includes user-term partitions, each user-term partition comprising temporal databases. As a post is received from a user, a user identifier, a post identifier, and a post is extracted. An object store communicatively coupled to a temporal database for recently received content is queried to determine whether terms in the post has already been stored. A term identifier is stored in the user-term index with the user and post identifiers. A forward index stores the post by post identifier. Responsive to a search query, the user-term index is searched by the user's connections and the terms. A real time search engine compiles the results of the user-term index query and retrieves the stored posts from the forward index. The search results may then be ranked and cached before presentation to the searching user.

Abstract translation: 公开了在社交网络系统中索引和检索实时内容。 用户术语索引包括用户术语分区，每个用户术语分区包括时间数据库。 当从用户接收到帖子时，提取用户标识符，帖子标识符和帖子。 查询通信地耦合到最近接收的内容的时间数据库的对象存储库，以确定该帖子中的术语是否已被存储。 术语标识符与用户和职位标识符一起存储在用户术语索引中。 转发索引以邮件标识符存储帖子。 响应于搜索查询，用户术语索引由用户的连接和术语搜索。 实时搜索引擎编译用户术语索引查询的结果，并从前向索引检索存储的帖子。 然后可以在向搜索用户呈现之前对搜索结果进行排序和缓存。
