QueryBuilders.queryString() does not seems to work properly for me

Elastic Stack Elasticsearch

Even below code is not working :frowning:

SearchResponse response =

client.prepareSearch("default").setTypes("Tweet")
.setSearchType(SearchType.DFS_QUERY_THEN_FETCH)
.setQuery(QueryBuilders.wildcardQuery("message","was"))
.setFrom(0).setSize(60).setExplain(false)
.execute()
.actionGet();
