Set index

Set up mapping

Set the mappings information of the current index library

{
	"mappings":{
		"govBaseLog":{
			"properties":{
				"id":{
					"type":"long",
					"store":true
				},
				"title":{
					"type":"text",
					"store":true,
					"index":true,
					"analyzer":"standard"
				},
				"content":{
					"type":"text",
					"store":true,
					"index":true,
					"analyzer":"standard"
				}
			}
		}
	}
}

govBaseLog type name, definition of table name

properties attribute, definition of table fields

id field name type type long long integer store true store index not_analyzed not indexed, the default is not indexed, set to analyze is the index  

It is equivalent to the definition of whether all the fields under a table are stored or not, index or analyzer

Set the mapping information after creating the index

		"helloWorld":{

				},
				"content":{
					"type":"text",
