Schema Defination

Hi

Im trying to crate schema for below data structure

{
"student" : {
"name" : "John",
"subject" : [1957, 1952]
}
}

In this, subject has to take array of values, I have defined my schema as

{
"student" : {
"properties" : {
"name" : {"type" : "string"},
"lists" : {
"properties" : {
"subject" : {"type" : "string"}
}
}
}
}
}

Is it a right structure ?

Looks almost like you're looking for the mapping of this "schema". How about:

{
  "mappings": {
    "type1": {
      "properties": {
        "student": {
          "type": "nested"
          "properties": {
            "name" :{
                "type": "string"
            }
            "subject": {
                "type" : "array"
            }
          }
        }
      }
    }
  }
}

The field student can be either nested or object. Read more about nested object here to see if it fits your use case.

What does lists come from? Also, the elements of the subject array are integers, not strings. This should be better:

{
  "student" : {
    "properties" : {
      "name" : {"type" : "string"},	
      "subject" : {"type" : "integer"}
    }
  }
}
