Hi all,

I am using elasticsearch to search through my logs. The data I am searching  
through is really large. I am using sync query using the function  
"query\_then\_fetch".  
But when I set large "size" (more than 10,000) using "builder.setSize" I see  
following OutOfMemory error:  
  
Exception in thread "elasticsearch[search]-pool-3-thread-1"  
java.lang.OutOfMemoryError: Requested array size e  
at  
org.apache.lucene.util.PriorityQueue.initialize(PriorityQueue.java:108)  
at  
org.apache.lucene.search.ShardFieldDocSortedHitQueue.(ShardFieldDocSortedHitQueue.java:48)  
at  
org.elasticsearch.search.controller.SearchPhaseController.sortDocs(SearchPhaseController.java:189)

Is there any way to know how much "size" (builder.setSize) can be set before  
we get this OutOfMemory error.

Thanks and Regards,  
Komal.

(I tried to post this using web interface but I got failure notification,  
hence mailing it. Sorry if this message appears twice.)
