Hi,

I am querying elasticsearch for multiple parallel requests using single transport client instance in my application.

I got the below exception for the parallel execution. Hot to overcome the issue.

Hello,

I assume you query lots of shards/indices? If not, then it might just be  
that ES is overloaded with that many requests and you have to add nodes.

If yes, you'll can increase the queue size of the search thread pool.  
Something like:

curl -XPUT localhost:9200/\_cluster/settings -d '{  
"persistent" : {  
"threadpool.search.size" : 5000  
}  
}'

Note that ES will use more memory to keep the search requests until they  
get executed.

## Best regards, Radu
