5 // The eventual goal is to provide a json backend to fetch content and fill the current page.
6 // The page will be filled in on the frontend using javascript.
7 // At the present time this page is based on "network", but the hope is to extend to serving
8 // any content (wall, community, search, etc.).
9 // All search parameters, etc. will be managed in javascript and sent as request params.
10 // Security will be managed on the backend.
11 // There is no "pagination query", but we will manage the "current page" on the client
12 // and provide a link to fetch the next page - until there are no pages left to fetch.
13
14 // With the exception of complex tag and text searches, this prototype is incredibly 
15 // fast - e.g. one or two milliseconds to fetch parent items for the current content, 
16 // and 10-20 milliseconds to fetch all the child items.
