Where clause in elasticsearch UpdateRequest

Question

I have an elasticsearch index where the id is auto-generated. When the need comes to update any document I have to search the document (using other parameters) to get the id first and then use this id in the update request.

Is there a way in which I can provide the where clause in update request itself?

Answer 1

You can use the Script functionality of UpdateRequest. The where condition can be provided using if statement.

Example:

updateRequest.script(new Script(ScriptType.INLINE, "painless",
    "if (ctx._source.userName== 'XXX') {ctx._source.age= '21'}",Collections.emptyMap()));
