Elastic Stack Elasticsearch
1

hi. Im curious about have any limit about MultiSearchRequestBuilder ?
My issue is :
i try create one MultiSearchRequestBuilder . And add more SearchRequestBuilder in

Like example : 
    create MultiSearchRequestBuilder empty
    for(int i=0;i< 9999;;i++ )
    {
     (create SearchRequestBuilder)
    (add SearchRequestBuilder  in  MultiSearchRequestBuilder )
    }
    MultiSearchREspone = MultiSearchRequestBuilder .action.get

Like that. I stuck in this very long time. Because i loop more .
Have any thing call : limit in MultiSearchRequestBuilder ?
And anybody know anyway search more query in only one call server elasticsearch?
Pls tell me :slight_smile: Thanks for your help
