Social distance based search result order adjustment

摘要

Both search criteria and a friends list associated with a user are obtained. One or more data items that satisfy the search criteria are identified as search results. An order of the search results is adjusted based at least in part on multiple additional friends lists, each of which is associated with a data item of the one or more data items. Each of the multiple additional friends lists can also be updated to reflect changes in the friends lists made by users associated with the friends lists.
