语法1.
PUT /索引库名/_mapping/类型名称
{
"properties": {
"字段名": {
"type": "类型",
"index": true，
"store": true，
"analyzer": "分词器"
}
}
}语法2.
PUT /索引库名
{
"mappings": {
类型名称: {
"properties": {
字段
}
}
}
}语法1和语法2是一个意思吗？
语法3：
POST /cars/transactions/_bulk
{ "index": {}}
{ "price" : 10000, "color" : "red", "make" : "honda", "sold" : "2014-10-28" }
{ "index": {}}
{ "price" : 20000, "color" : "red", "make" : "honda", "sold" : "2014-11-05" }
{ "index": {}}
{ "price" : 30000, "color" : "green", "make" : "ford", "sold" : "2014-05-18" }
{ "index": {}}
{ "price" : 15000, "color" : "blue", "make" : "toyota", "sold" : "2014-07-02" }
{ "index": {}}
{ "price" : 12000, "color" : "green", "make" : "toyota", "sold" : "2014-08-19" }
{ "index": {}}
{ "price" : 20000, "color" : "red", "make" : "honda", "sold" : "2014-11-05" }
{ "index": {}}
{ "price" : 80000, "color" : "red", "make" : "bmw", "sold" : "2014-01-01" }
{ "index": {}}
{ "price" : 25000, "color" : "blue", "make" : "ford", "sold" : "2014-02-12" }我知道语法3是批量提交，但是我发现每一个提交的row的上面都有{ "index": {}}这样的数据结构，它是为了设置什么吗？
语法1和语法2是一个意思
语法就是这样
POST example/docs/_bulk
{"index": {"_id": 1}}
{"id":1, "name": "admin", "counter":"10", "tags":["red", "black"]}
{"index": {"_id": 2}}
{"id":2, "name": "张三", "counter":"20", "tags":["green", "purple"]}
{"index": {"_id": 3}}
{"id":3, "name": "李四", "counter":"30", "tags":["red", "blue"]}
{"index": {"_id": 4}}
{"id":4, "name": "tom", "counter":"40", "tags":["orange"]}
