PUT test
{
"settings" : {
"number_of_shards" : 1
},
"mappings" : {
"_doc" : {
"properties" : {
"field1" : { "type" : "text" }
}
}
}
}
```
what does `_doc` means when creating a `index`?
Can I specific a `typename` instead of `_doc`, as `student` replacing `_doc`
```
PUT test
{
"settings" : {
"number_of_shards" : 1
},
"mappings" : {
"students" : {
"properties" : {
"field1" : { "type" : "text" }
}
}
}
}
```

That is the `_type`. This is deprecated and will be removed in 7.0, so we would suggest not using anything but that default value.

You should add this as a new field instead.

`/index/${typename}/`
I wanna create a mapping for this `type`
`/test/students` as for `students`
how does it become a `field` name other than a `typename`

Don't do that.
Put `"typename": "student"` in your document.

Sorry, I am quite new to elastic.
the purpose is to create a index name `test` and initialize the mapping of a `typename = "students"`
```
PUT test
{
"settings": {
"number_of_replicas": 1,
"number_of_shards": 1
},
"mappings" : {
"_doc" : {
"properties" : {
"field1" : { "type" : "text" }
}
}
}
}
```
above that's referring to the docs,
I am quite confusing here(what is `_doc` means here)
So I am intent to replace `_doc` to `students`, because `students` is my `table` name(in elastic world `typename`)
**probably I misused the word `typename`**
below is what I want as a result for each document
` _index: "test", _type: "students"`
As your said:
> Put `"typename": "student"` in your document.
I don't really know
1. where should I put my `"typename": "student"` to.
2. And how to achieve my purpose `initialize a index with a typename(table name) as well as set the mapping of the typename's fields`
Many thanks.

Do this;
```auto
PUT test
{
"settings": {
"number_of_replicas": 1,
"number_of_shards": 1
},
"mappings" : {
"_doc" : {
"properties" : {
"field1" : { "type" : "text" },
"typename" : { "type" : "text" }
}
}
}
}
```
Ignore `_doc`, ignore `_type`, they are deprecated features and using them will only cause more problems.

Sorry, I thought you still misunderstand.
I wanna the type be the table name . like this `test/students/1`
And, specify the filed such as `name, gender, id, age` of `students` not on `index`,
`_index: "test", _type: "students"`
So, I am intent to do
```
PUT test
"mappings" : {
"students" : {
"properties" : {
"field1" : { "type" : "text" }
}
}
}
```

in your last reply
```
PUT test
{
"settings": {
"number_of_replicas": 1,
"number_of_shards": 1
},
"mappings" : {
"_doc" : {
"properties" : {
"field1" : { "type" : "text" },
"typename" : { "type" : "text" }
}
}
}
}
```
I thought you still used the `_doc`.
Is there something I misunderstand about `mappings`?

Please read [https://www.elastic.co/blog/removal-of-mapping-types-elasticsearch](https://www.elastic.co/blog/removal-of-mapping-types-elasticsearch).
As I have been saying - Do Not Use Types. They will be removed very soon.
If you use this type then you will need to make more changes in the very near future.
