Mapper: Ability to disable storing the "source" field

[kimchy]

The source field is used to store the actual json that was indexed. Have the ability to disable storing it.

Disclaimer: Some features in elasticsearch might, in the future, require accessing the source field. When disabled, this features will simply not work. It is preferable to keep it on.

Disabling the source field can be done using the following mapping:

{
    person : {
        dateFormats : ["yyyy-MM-dd", "dd-MM-yyyy"],
        sourceField : {enabled : false}
    }
}

It can be disabled for all dynamic mappings created using the shared dynamic mapping definition.
