elasticsearch 索引操作api

创建一个索引： king_test_person

PUT /king_test_person
{
    "settings": {
        "refresh_interval": "1s",
        "number_of_shards": "3",
        "number_of_replicas": "2"
    },
    "mappings": {
        "properties": {
            "person_id": {
                "type": "long"
            },
            "name": {
                "type": "keyword"
            },
            "name_pinyin": {
                "type": "text",
                "analyzer": "pinyin"
            },
            "sex": {
                "type": "integer"
            },
            "nationality": {
                "type": "keyword"
            },
