-//        "index": should become time field (or not)
-//        "snippet": the text of the item
-//        "source": text describing source (i.e., "New York Post")
-//        "thumbnail": URL of thumbnail on popgadget server
 //        "title": text giving title of item
 //        "url": link to item's page
 //    },
 //    [up to number of items in kMaxWebResourceCacheSize]
