If you set ignore_malformed string to false. It would not index the document if it is malformed but throws an exception. At least in elasticsearch 1.6.0.

Example:

put test

put test/test/_mapping 
{
    "properties" : {
        "title" : {"type" : "string"},
        "data" : {"type": "long" ,"ignore_malformed":false}

    }
}

put test/test/1
{
    "data" : "1",
    "title" : "valid coerce string to number"
}

put test/test/2
{
    "data" : "hello",
    "title" : "invalid number"
}

#Failed Response
{
   "error": "MapperParsingException[failed to parse [data]]; nested: NumberFormatException[For input string: \"hello\"]; ",
   "status": 400
}

Query with Get fails

get test/test/2


{
   "_index": "test",
   "_type": "test",
   "_id": "2",
   "found": false
}
