Elasticsearch transport client cannot handle too much data?


here is my code:

" SearchRequestBuilder builder = client.prepareSearch("index")
BoolQueryBuilder qb = QueryBuilders.boolQuery()
.must(new QueryStringQueryBuilder("English").field("language"));"

I want to query 200000 documents from a remote elasticsearch server, but it throws me error like

"Sep 24, 2014 3:30:28 PM org.elasticsearch.transport
Warnung: Transport response handler not found of id [86]"

could it because I try to query too much data, so that it is overloaded? It is no problem to query 100000. There are even much more data than 1000000.

Does someone know the problem? Thanks!
