HistoricalCriteriaSearch - More detailed example

Hi, we currently try to make a HistoricalCriteriaSearch request. Looks like we are doing something wrong and we have the feeling that there are 'hidden' dependencies regarding the available search fields. We are performing the following request:

{
"Request": {
"RicPattern": "^DTEGn",
"CurrencyCodes": [ "EUR" ],
"OptionMonthCodes": ["X" ],
"Range": {
"Start": "2016-11-07T00:00:00.000Z",
"End": "2017-11-08T00:00:00.000Z"
}
}
}

And we get this response:

{
"error": {
"message": "Gateway ETH returned error status code: BadRequest from (http://rp.cp.hdc.reuint.com/TickHistoryWS/search) Error ID: [29427a15-c7e9-4079-9183-216ee22f14c2]"
}
}

Can you please advice? We need this search request to lookup expired options and futures, and we really rely on this...

Thx in advance!
