Join like operation java

i have two indices employee and organisation, both are linked via a common attribute organisationId. i want to do a search where searchString will be matched with EmpName, EmpDesignation and organisationName, and search should return me the employee object.


  • searchString "james", result should return the employee object from employee index having name as james.
  • searchString "developer", result should return the employee objects from employee index who are developer.
  • searchString "microsoft", result should return the organisationId of microsoft from organisation index which will be used to search all employee objects from employee index who belong to microsoft.(Here i need a join like operation).


SearchRequest searchRequest = new SearchRequest("indexA","indexB");

SearchSourceBuilder searchSourceBuilder = new SearchSourceBuilder();
Map<String,Float> fields = new HashMap<String, Float>();
fields.put("column1_From_IndexA", 0.0F);
fields.put("column2_From_IndexA", 0.0F);
fields.put("column1_From_IndexB", 0.0F);

QueryStringQueryBuilder builder = QueryBuilders.queryStringQuery("searchString").fields(fields);


SearchResponse response =, RequestOptions.DEFAULT);

this code snippet return the combination of everything which is messy.

please suggest how to achieve this.
Thanks in advance.

Could you provide a full recreation script as described in About the Elasticsearch category. It will help to better understand what you are doing. Please, try to keep the example as simple as possible.

A full reproduction script will help readers to understand, reproduce and if needed fix your problem. It will also most likely help to get a faster answer.

Please do it with a pure Kibana script and not with Java code as it would be harder to reproduce.
