这可以通过为特定字段指定“index”：false来实现。现在的问题是如何在spark中复制它。

PUT hostname:9200/index1

{
    "index1": {
        "aliases": {},
        "mappings": {
            "properties": {
                "business_address": {
                    "type": "text",
                    "index": false,
                    "fields": {
                        "keyword": {
                            "type": "keyword",
                            "ignore_above": 256
                        }
                    }
                },
                "business_city": {
                    "type": "text",
                    "fields": {
                        "keyword": {
                            "type": "keyword",
                            "ignore_above": 256
                        }
                    }
                }
