重新指定文档类型映射拼音分词类型

POST /jd_goods/_mapping
{
        "properties": {
            "title": {
                "type": "text",
                "analyzer": "ik_max_word_pinyin",
                "search_analyzer": "ik_smart_pinyin"
            },
            "desc": {
                "type": "text",
               "analyzer": "ik_max_word_pinyin",
               "search_analyzer": "ik_smart_pinyin"
            },
            "img": {
                "type": "text"
            },
            "price": {
                "type": "text"
            }
