Hi,  
we have many indexes each with one or more aliases each with one shard and  
each created from same template.  
I want to fire scroll search with limit to one or more indexes by one or  
more aliases. If I set a size parameter its applied to result from a shard  
not to whole result which i've expected. If i set a post limit filter then  
no data are returned.  
I want to set size to ONE and get ONE result even if i hit a 15 shards. Now  
i gets 15 results or nothing.  
What's wrong?

String[] aliases = getAliases(input);  
SearchRequestBuilder requestBuilder = esConnection.prepareSearch(aliases);

BoolQueryBuilder boolQuery = boolQuery();  
boolQuery =  
boolQuery.must(rangeQuery("created\_time").from(input.getTimeFrom()).to(input.getTimeTo()));  
...  
requestBuilder.setQuery(boolQuery);

requestBuilder.setSearchType(SearchType.SCAN);  
requestBuilder.setTypes("type");  
requestBuilder.addSort("created\_time", SortOrder.DESC);  
requestBuilder.setExplain(false);  
requestBuilder.setFetchSource(false);  
requestBuilder.setNoFields();  
requestBuilder.setSize(input.getLimit());  
//  
requestBuilder.setPostFilter(FilterBuilders.limitFilter(input.getLimit()));  
requestBuilder.setScroll(new TimeValue(1, TimeUnit.MINUTES));

ListenableActionFuture execute = requestBuilder.execute();  
SearchResponse searchResponse = execute.actionGet();

searchResponse =  
esConnection.prepareSearchScroll(searchResponse.getScrollId())  
.execute().actionGet();

SearchHits hits = searchResponse.getHits();  
List result = new ArrayList\<\>();  
for (SearchHit searchHit : hits.getHits()) {  
result.add(searchHit.getId());  
}
