I used upsert API and print UpdateResponse ```auto StringBuilder sb = new StringBuilder(); sb.append("{\"_index\":\"").append(response.getIndex()).append("\",\"_type\":\"") .append(response.getType()).append("\",\"_id\":\"").append(response.getId()) .append("\",\"_version\":\"").append(response.getVersion()) .append("\",\"created\":\"").append(response.isCreated()).append("}"); ``` and I found below resposne: ```auto {"_index":"bs-list_r","_type":"list","_id":"1031438199","_version":"2","created":"true} ``` so my question is: why created doc has \_version 2? is it by design or is it a bug? if it is by design, can give more description or share some useful info please. ---

are u saying that I upsert data with giving certain version number? if so, I am telling u that I am not. I am not giving any version number when I upsert document. most of the docs' version is 1 when create=true, only a few with 2. ---
