Elasticsearch不允許索引空日期字段

Question

我有波紋管的數據索引：

array:6 [▼ 
    "index" => "my_index" 
    "type" => "audit_field" 
    "id" => "57f36d28a1dfc" 
    "parent" => "57f36d289f1b2" 
    "routing" => 318 
    "body" => array:19 [▼ 
    "session_id" => 318 
    "trans_seq_no" => 13 
    "table_seq_no" => 13 
    "field_id" => 65 
    "field_name" => "id" 
    "new_value" => 45 
    "old_value" => 45 
    "date_type_new_value" => null 
    "date_type_old_value" => null 
    "time_type_new_value" => null 
    "time_type_old_value" => null 
] 
] 

我已經定義了自己的映射，波紋管

array(
    'index' => 'promote_kmp', 
    'type' => 'audit_field', 
    'body' => [ 
     'audit_field' => [ 
      '_source' => [ 
       'type' => 'string' 
      ], 
      "_parent" => [ 
       "type" => "audit_table" 
      ], 
      'properties' => [ 
       'session_id' => array('type' => 'string'), 
       'trans_seq_no' => array('type' => 'string'), 
       'table_seq_no' => array('type' => 'string'), 
       'field_id'  => array('type' => 'string'), 
       'field_name' => array('type' => 'string'), 
       'old_value' => array(
        'type' => 'string' 
       ), 
       'new_value' => array(
        'type' => 'string' 
       ), 
       'date_type_new_value' => array(
        'type' => 'date', 
        'format' =>'YYYY-MM-dd HH:mm:ss||YYYY-MM-dd||MM/dd/yyyy||yyyy/MM/dd' 
       ), 
       'date_type_old_value' => array(
        'type' => 'date', 
        'format' =>'YYYY-MM-dd HH:mm:ss||YYYY-MM-dd||MM/dd/yyyy||yyyy/MM/dd' 
       ), 
       'time_type_new_value' => array(
        'type' => 'date', 
        'format' => 'HH:mm:ss' 
       ), 
       'time_type_old_value' => array(
        'type' => 'date', 
        'format' => 'HH:mm:ss' 
       ) 
      ] 
     ] 
    ] 
); 

但是，當我婉與空索引數據在日期字段中，elasticsearch顯示和不能使用映射日期格式類型解析日期字段值的異常。 如何解決這個問題，我也嘗試了空的，但不工作，並給出相同的信息。

MapperParsingException[failed to parse [date_type_new_value]]; nested: 
MapperParsingException[failed to parse date field [], tried both date format 
[YYYY-MM-dd HH:mm:ss||YYYY-MM-dd||MM/dd/yyyy||yyyy/MM/dd], and timestamp 
number with locale []]; nested: IllegalArgumentException[Invalid format: ""]; 

Answer 1

我不知道爲什麼空不工作，我可以索引空值在1.7 ES，也IllegalArgumentException[Invalid format: ""];表明空字符串，而不是空值。

如果您無法控制數據，則需要使用ignore_malformed，它不會爲日期字段建立索引，而是正常地爲文檔建立索引。
