Is it possible to have automatic id generation on bulk create?  
What is the syntax? Leaving out the \_id?

{ "create" : { "\_index" : "test", "\_type" : "type1"} }  
{ "field1" : "value3" }

Yep, this should work.

Hello ,  
I have a doubt at "index,type,id" for elastic search. I had a data and converted in json and seen code below like "index,type,id" of each&every data. How can I actually do it? I've checked some tutorials and could not understand.

Ex:{ "index" : { "index" : "pokedex", "type" : "pokemon", "\_id" : "1" } }  
{ "ndex": 1, "name": "Bulbasaur" }  
{ "index" : { "index" : "pokedex", "type" : "pokemon", "\_id" : "2" } }  
{ "ndex": 2, "name": "Ivysaur" }  
{ "index" : { "index" : "pokedex", "type" : "pokemon", "\_id" : "3" } }  
{ "ndex": 3, "name": "Venusaur"}

How did we take or automated this format like { "index" : { "index" : "pokedex", "type" : "pokemon", "\_id" : "1" } }, here "id" will change everytime along with the data.  
Thanks, advance.
