Using scrolls in Java

Read the scroll documentation first!

import static org.elasticsearch.index.query.QueryBuilders.*;

QueryBuilder qb = termQuery("multi", "test");

SearchResponse scrollResp = client.prepareSearch(test)
        .addSort(SortParseElement.DOC_FIELD_NAME, SortOrder.ASC)
        .setScroll(new TimeValue(60000))
        .setQuery(qb)
        .setSize(100).execute().actionGet(); //100 hits per shard will be returned for each scroll
//Scroll until no hits are returned
while (true) {

    for (SearchHit hit : scrollResp.getHits().getHits()) {
        //Handle the hit...
    }
    scrollResp = client.prepareSearchScroll(scrollResp.getScrollId()).setScroll(new TimeValue(60000)).execute().actionGet();
    //Break condition: No hits are returned
    if (scrollResp.getHits().getHits().length == 0) {
        break;
    }
}

The size-parameter is per shard, so if you run a query against multiple indices (leading to many shards being involved in the query) the result might be more documents per execution of the scroll than you would expect!
