如果文档的字段映射不匹配，Elasticsearch静默失败

如果将ignore_malformed 字符串设置为false。如果文档格式不正确，但会引发异常，则不会索引该文档。至少在elasticsearch 1.6.0中。

例：

put testput 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 failsget test/test/2{   "_index": "test",   "_type": "test",   "_id": "2",   "found": false}
