It would be nice if we provided a mechanism to query revisions for data. Atm we can only do queries on the latest data. Perhaps the endpoint could look something like: GLOBAL: <HOST>/1/topic/get/json/r/query;<QUERY> SINGLE: <HOST>/1/topic/get/json/<ID>/r/query;<QUERY> I imagine the data that should be able to be queried should be similar to a regular search, with the addition of being able to query for revisions between a date range.
