Filter中term和range不能同时用么？

有两个filter条件，应该怎么写？
 
GET test/_search
{
  "query": {
    "bool": {
      "filter": {
        "term": {
          "name": "kevin"
        },
        "range": {
          "age": {
            "gte": 20,
            "lte": 30
          }
        }
      }
    }
  }
}
 
会报错：
{
  "error": {
    "root_cause": [
      {
        "type": "parsing_exception",
        "reason": "[term] malformed query, expected [END_OBJECT] but found [FIELD_NAME]",
        "line": 8,
        "col": 9
      }
    ],
    "type": "parsing_exception",
    "reason": "[term] malformed query, expected [END_OBJECT] but found [FIELD_NAME]",
    "line": 8,
    "col": 9
  },
  "status": 400
}
