业务场景：

现在的系统设计不满足业务需求时就需要升级服务，为了满足业务需求有时需要对ES中字段进行添加或修改操作，接下来我们查看为 mappings 添加字段的相关操作：

在讲解添加字段的es原生API之前，我看先来说下查看ElasticSearch中索引信息的相关API:

一、查看索引Setting配置信息

GET  http://xxx.xxx.xxx.xxx:9200/supplier_index/_settings
{
    "supplier_index": {
        "settings": {
            "index": {
                "refresh_interval": "1s",
                "number_of_shards": "2",
                "provided_name": "supplier_index",
                "creation_date": "1528175417715",
                "analysis": {
                    "filter": {
                        "pinyin_first_letter_and_full_pinyin_filter": {
                            "keep_joined_full_pinyin": "true",
                            "keep_none_chinese_in_first_letter": "true",
                            "lowercase": "true",
                            "keep_original": "false",
                            "keep_first_letter": "true",

                            "keep_full_pinyin": "false"
                        },

                        "full_pinyin_filter": {
                            "keep_joined_full_pinyin": "true",
                            "keep_none_chinese_in_first_letter": "true",
