Re: ES for storing index alone.

[Cyril Cherian]

Thanks David,

I still have some doubts in teh approach you sent.
I am using Elastic version 1.1.1

1) I created a mapping called tests
2) Created a mapping 
curl -XPUT 'http://localhost:9200/tests/_mapping/test' -d '
{
    "test" : {
        "properties" : {
           * "_source" : {"enabled" : false},*
            "message" : {"type" : "string" },
            "projectId": {"type": "string" },
            "userName": {"type": "string"}
        }
    }
}
'
3) Inserted some values inthe index
Example:
curl -XPUT 'http://localhost:9200/tests/test/1' -d '{
        "message" : "Cyril here",
        "projectId": "1234",
        "userName": "rahul"
}'

curl -XPUT 'http://localhost:9200/tests/test/1' -d '{
        "message" : "a message Cyril here",
        "projectId": 134,
        "userName": "cyril"
}'

4) Now when i do a search 
like http://localhost:9200/tests/test/_search?q=%22message%22

I get _source (which i am not expecting)...what i want to achieve is that 
elastic should just index the data but not store the data.

"hits": [ <http://localhost:9200/tests/test/_search?q=%22message%22#>

      { <http://localhost:9200/tests/test/_search?q=%22message%22#>

        "_index": "tests",
        "_type": "test",
        "_id": "1",
        "_score": 0.11506981,
        "_source": { <http://localhost:9200/tests/test/_search?q=%22message%22#>

          "message": "a message Cyril here",
          "projectId": 134,
          "userName": "cyril"
        }

      }

    ]


Let me know if I am missing on something.
