We create branches:

Using python with function_score

Let's say you want to use function_score API using python. Here is a way of doing it:

curl -XDELETE "http://localhost:9200/test"

curl -XPUT "http://localhost:9200/test/doc/1" -d '{
  "num": 1.0
}'

curl -XPUT "http://localhost:9200/test/doc/2?refresh" -d '{
  "num": 2.0
}'

curl -XGET "http://localhost:9200/test/_search?pretty" -d'
{
  "query": {
    "function_score": {
      "script_score": {
        "script": "doc[\"num\"].value * _score",
        "lang": "python"
      }
    }
  }
}'

gives

{
   // ...
   "hits": {
      "total": 2,
      "max_score": 2,
      "hits": [
         {
            // ...
            "_score": 2
         },
         {
            // ...
            "_score": 1
         }
      ]
   }
}

Using python with script_fields

curl -XDELETE "http://localhost:9200/test"

curl -XPUT "http://localhost:9200/test/doc/1?refresh" -d'
{
  "obj1": {
   "test": "something"
  },
  "obj2": {
    "arr2": [ "arr_value1", "arr_value2" ]
  }
}'

curl -XGET "http://localhost:9200/test/_search" -d'
{
  "script_fields": {
    "s_obj1": {
      "script": "_source[\"obj1\"]", "lang": "python"
    },
    "s_obj1_test": {
      "script": "_source[\"obj1\"][\"test\"]", "lang": "python"
    },
    "s_obj2": {
      "script": "_source[\"obj2\"]", "lang": "python"
    },
    "s_obj2_arr2": {
      "script": "_source[\"obj2\"][\"arr2\"]", "lang": "python"
    }
  }
}'

gives

{
  // ...
  "hits": [
     {
        // ...
        "fields": {
           "s_obj2_arr2": [
              [
                 "arr_value1",
                 "arr_value2"
              ]
           ],
           "s_obj1_test": [
              "something"
           ],
           "s_obj2": [
              {
                 "arr2": [
                    "arr_value1",
                    "arr_value2"
                 ]
              }
           ],
           "s_obj1": [
              {
                 "test": "something"
              }
           ]
        }
     }
  ]
