    • 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.

    • A method and system for static resource caching in a networking system are provided. The system includes a fetcher instantiated on a particular user device. The fetcher can be a browser plug-in, a separate process or a program integrated into another process on the particular user device. The fetcher downloads static resource data from a web server and groups the downloaded static resource data into a plurality of static resource packages. In some embodiments, the fetcher may predict new static resource package(s) that the particular user may need by analyzing the particular user's activities on the web server and web traffics on the particular user device. Therefore, static resource data from the web server may be effectively cached on the particular user device even before any browser is launched on the particular user device.
    • 提供了一种用于网络系统中静态资源缓存的方法和系统。 该系统包括在特定用户设备上实例化的提取器。 提取器可以是浏览器插件,单独的进程或集成到特定用户设备上的另一进程的程序。 提取器从Web服务器下载静态资源数据,并将下载的静态资源数据分组到多个静态资源包中。 在一些实施例中,提取器可以通过分析特定用户在web服务器上的活动和特定用户设备上的web流量来预测特定用户可能需要的新的静态资源包。 因此,即使在特定用户设备上启动任何浏览器之前,来自web服务器的静态资源数据也可以被有效地缓存在特定用户设备上。
