Hi,

I am trying to assign \_timestamp to a property when I post to ElasticSearch. Something is wrong and I have been staring at this for a while now. ThnX in advance for any pointers.

GET /persons/\_mapping/family

"family": {  
"\_timestamp": {  
"enabled": true,  
"store": true,  
"path": "family.create\_date",  
"format": "yyyy-MM-dd HH:mm:ss",  
"ignore\_missing": true  
},  
"properties": {  
"about": {  
"type": "string"  
},  
"age": {  
"type": "integer"  
},  
"create\_date": {  
"type": "date",  
"format": "dateOptionalTime"  
},  
"first\_name": {  
"type": "string"  
},  
"interests": {  
"type": "string"  
},  
"last\_name": {  
"type": "string"  
}  
}  
}

POST /persons/family  
{  
"first\_name" : "me\_myself",  
"last\_name" : "\_and\_I",  
"age": "00",  
"about" : "I love to figure things out",  
"interests": ["photography", "running", "chocolate", "music"]  
}

GET /persons/family/\_search

```
  "hits": [
     {
        "_index": "persons",
        "_type": "family",
        "_id": "AU3HyMph3okB74YfFVvn",
        "_score": 1,
        "_source": {
           "first_name": "me_myself",
           "last_name": "_and_I",
           "age": "00",
           "about": "I love to figure things out",
           "interests": [
              "photography",
              "running",
              "chocolate",
              "music"
           ]
        }
     },
```
