elasticsearch

解决方案是使用

.value

{  "script_fields": {    "new_date_field": {      "script": {        "inline": "doc['date_field'].value + 14400"      }    }  }}

但是，我实际上想将其用于重新索引，但格式略有不同。这是我在

_reindex

POST _reindex{  "source": {    "index": "some_index_v1"  },  "dest": {    "index": "some_index_v2"  },  "script": {    "inline": "def sf = new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ss"); def dt = sf.parse(ctx._source.date_field); def calendar = sf.getCalendar(); calendar.setTime(dt); def instant = calendar.toInstant(); def localDateTime = LocalDateTime.ofInstant(instant, ZoneOffset.UTC); ctx._source.date_field = localDateTime.plusHours(4);"  }}

这是可读版本的内联脚本

def sf = new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ss");def dt = sf.parse(ctx._source.date_field);def calendar = sf.getCalendar();calendar.setTime(dt);def instant = calendar.toInstant();def localDateTime = LocalDateTime.ofInstant(instant, ZoneOffset.UTC);ctx._source.date_field = localDateTime.plusHours(4);

这是无痛支持的功能列表，很痛苦。
