Trivial Steps to reproduce:
{
  "jsonrpc": "2.0",
  "method": "event.get",
  "params": {
    "output": [
      "eventid",
      "value",
      "r_eventid"
    ],
    "value": "1",
    "search": {
      "r_eventid": "0"
    },
    "startSearch": true,
    "limit": 5
  },
  "id": 1
}
Result:
{
  "jsonrpc": "2.0",
  "result": [
    {
      "eventid": "3761654",
      "value": "1",
      "r_eventid": "0"
    },
    {
      "eventid": "4083768",
      "value": "1",
      "r_eventid": "0"
    },
    {
      "eventid": "5171834",
      "value": "1",
      "r_eventid": "5171926"
    },
    {
      "eventid": "5171837",
      "value": "1",
      "r_eventid": "5171840"
    },
    {
      "eventid": "5171839",
      "value": "1",
      "r_eventid": "5171844"
    }
  ],
  "id": 1
}
Expected:
Only active/open/problem/not resolved events, with r_eventid = 0, meaning the event is still not resolved.
If I have missed some parameter to filter such events, please advise how to do it.
