## I use the same query to search something by scrolls for many times,each time the search result are big different.i check the ES log find somethig like this: ========================es log=================================== [2013-05-06 11:57:08,774][DEBUG][action.search.type] [node6] [1924] Failed to execute query phase org.elasticsearch.transport.RemoteTransportException: [node3][inet[/10.0.0.3:9300]][search/phase/scan/scroll] Caused by: org.elasticsearch.search.SearchContextMissingException: No search context found for id [1924] at org.elasticsearch.search.SearchService.findContext(SearchService.java:459) at org.elasticsearch.search.SearchService.executeScan(SearchService.java:208) at org.elasticsearch.search.action.SearchServiceTransportAction$SearchScanScrollTransportHandler.messageReceived(SearchServiceTransportAction.java:697) at org.elasticsearch.search.action.SearchServiceTransportAction$SearchScanScrollTransportHandler.messageReceived(SearchServiceTransportAction.java:686) at org.elasticsearch.transport.netty.MessageChannelHandler$RequestHandler.run(MessageChannelHandler.java:268) at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1110) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:603) at java.lang.Thread.run(Thread.java:722)

javacode like this:

SearchResponse response =  
client.prepareSearch(getIndexNames(query)).setTypes("post")  
.setSearchType(SearchType.SCAN)  
.setScroll(new TimeValue(1000))  
.setQuery(qb)setSize(5000).execute().actionGet();  
......  
response = client.prepareSearchScroll(response.getScrollId())  
.setScroll(new TimeValue(1000000))  
.execute()  
.actionGet();  
......
