创建索引（及映射）

PUT apple

{
	"settings": {
		"number_of_shards": 5,
		"number_of_replicas": 1
	},
	"mappings": {
		"apple_type": {
			"properties": {
				"id": {
					"type": "long"
				},
				"code": {
					"type": "keyword"
				},
				"unit": {
					"type": "keyword"
				},
				"price": {
					"type": "integer"
				},
				"create_time": {
					"type": "date"
				},
				"create_user": {
					"type": "keyword"
				}
			}
		}
	}
}

注意两个String类型

ES在5.0以后对String类型做了细分：

keyword：不进行分词，直接索引；

text：会分词，然后进行索引；
