Abstract: Methods, systems, and computer-readable media are provided for updating a search index with new uniform resource locators (URLs) and with metadata for new and known URLs. Data associated with communications made by users using a social network is received. The communications include a URL therein that a user has shared, posted, or otherwise communicated to one or more other users using the social network. When the URL is not found in a search index it is identified as a new URL and is added to the search index. A measure of a trending interest, or virality, of the URL is determined from the data. The determined virality is associated with the URL in a search index as metadata. The virality is useable to inform a ranking of the URL against a plurality of other URLs for identification and presentation as a search result in a search engine results page.

Abstract: Systems, methods, and computer-readable storage media for presenting supplemental search results having indications that identified documents have been endorsed by the user and/or social network connections of the user are provided. A search query is received and it is determined that the user's social networking data is available. Documents that have been endorsed by the user and/or social network connections of the user are searched to identify those that satisfy the input search query. The satisfying documents are assigned a relevance score to determine whether each satisfying document is relevant enough to be shown and to determine placement of the document on the SERP relative to standard search results. Upon rendering of the SERP, a supplemental search result identifying documents that were endorsed by the user and/or social network connections of the user is presented, as is an indication about which social network connection(s) of the user endorsed the document.
