How to detect whether elasticsearch has enabled dynamic field-CodePudding

I don't know whether my index has enabled/disabled dynamic field. When I use get index mapping command it just responses these informations:

GET /my_index1/_mapping

{
    "my_index1": {
        "mappings": {
            "properties": {
                "goodsName": {
                    "fields": {
                        "keyword": {
                            "ignore_above": 256,
                            "type": "keyword"
                        }
                    },
                    "type": "text"
                },
                "auditTime": {
                    "type": "long"
                },
                "createUserId": {
                    "type": "long"
                }
            }
        }
    }
}

CodePudding user response：

If you don't explicitly set the dynamic to false or strict, it will be true by default. If you explicitly set that, you will see that in your mappings:

{
    "mappings": {
        "dynamic": false,
        "properties": {
            "name": {
                "type": "text"
            }
        }
    }
}

And when you index the following document:

{"name":"products", "clickCount":1, "bookingCount":2, "isPromoted":1}

Only the field name will be indexed, the rest won't. If you call the _mapping endpoint again, it will give you the exact mappings above.
