Query date range

[denisvolokh]

Hi,

I have a problem with building filter on a timestamp field.

I have defined filter in my MarketDataResource(resources.MongoEngineResource)
filtering = { "instrument" : ALL, "timestamp" : ["gte", "lte", "range"], }

and when I do query on timestamp field I receive error

'exact' is not an allowed filter on the 'timestamp' field.

Here is my query

api/v1/marketdata/?format=json&instrument=Z74&timestamp__gte=2016-03-18T00:00:00.000+0000&timestamp__lse=2016-03-18T01:00:01.016+0000

But query works when I query only gte or only lte.

Could you help me to understand what is wrong with my query?

Thanks.
