elasticsearch python api overwrites the existing field

I'm using ElasticSearch Python API, I found if the _id is same the old data would be overwritten. e.g. I had name="Tom", right now I index the same _id with field age=30. I found the name="Tom" was removed after the reindex. The right result I hope age=30 only appended to the existing index. Should I tune any parameters please?

I'm using the following code:

from elasticsearch import Elasticsearch
es = Elasticsearch("http://10.0.0.1:9200")
res = es.index(index="panavstream", doc_type='panav', id="123", body=doc)

Thanks in Advance

update function with script body can append a field in data. elasticsearch-py update

the sample:

doc = {
  'script' : 'ctx._source.age = 30'
}
es.update(index="panavstream", doc_type='panav', id="123", body=doc)
