-// todo: time range beyond 30 days
-// - how + when to expand time range,
-// - how to de-dupe items from appearing twice when expanding time range... is tricky
+// todo: feed currently hard coded to go back: 1 YEAR
+// this is probably fine for now, as ES feed only went back 1 MONTH.
+// BUT if we want to support going back further:
+// - in a loop... start with @before = now()
+// - if len(rows) < limit, expand time range until limit is reached.
+// this could also work better if client sent some date hints...
+//
+// we could also get rid of date range filter... it would make feed slower...
+// but maybe it'd be okay?
