sir, I have go through document
request.setQuery(new TermQueryBuilder("user", "kimchy"));
this method is used to update all the document user to kimchy but i need to update same using condition like age < 20 for this what this what i need to use
sample sql query
update index1 set name to kimchy where father_name=ram

This is used to update all documents where user = "kimchy".

yes sir, but i need to update specific document using condition for what can i do?

You first need to understand how all this works before translating to Java code.
Have a look at https://www.elastic.co/guide/en/elasticsearch/reference/7.3/docs-update-by-query.html

Once you found the right syntax, you can share the code with us and we can hopefully help you to transform to Java code but it should be easy.

ok sir, there is no one like i would asked?
see i need to update salaries of employee whose ages are greater than 25 for this there is no dsl query types to update? here showing is only full documentation update what i need to do?

It's probably something like:

POST twitter/_update_by_query
  "script": {
    "source": "ctx._source.salary+=100",
    "lang": "painless"
  "query": {
    "range": {
      "age": {
        "gte": 25
