Filter on integer type filed thrown exception if the passed value is not correct integer format

[Youxu (Xudong You)]

My index has a field "Count" which is integer type and I would like to filter by this field as follows:

GET _search
{
  "query": {
    "filtered": {
      "query": {
        "match": {
          "text": "quick brown fox"
        }
      },
      "filter": {
        "term": {
          "Count": "100"
        }
      }
    }
  }
}

It works if the passed the value is in correct integer format. But if I passed an value with incorrect integer format, ES thrown exception:

GET _search
{
  "query": {
    "filtered": {
      "query": {
        "match": {
          "text": "quick brown fox"
        }
      },
      "filter": {
        "term": {
          "Count": "abc111"
        }
      }
    }
  }
}

exception:
  "caused_by": {
            "type": "number_format_exception",
            "reason": "For input string: \"abc111\"

Is there an elegant way to suppress the exception even the passed value is no in correct integer format?
