ES5.x版本下，suggestion 的java API问题

网上的参考例子如下，但是在5.5.1下 ，addSuggestion 方法没有了。
请教该版本5.5.1下，如何解决。
如有参考文档也可以，谢谢！

CompletionSuggestionBuilder compBuilder = new CompletionSuggestionBuilder("complete");
compBuilder.text("n..");
compBuilder.field("suggest");

SearchResponse searchResponse = localClient.prepareSearch(INDEX_NAME)
.setTypes("completion")
.setQuery(QueryBuilders.matchAllQuery())
.addSuggestion(compBuilder)
.execute().actionGet();

CompletionSuggestion compSuggestion = searchResponse.getSuggest().getSuggestion("complete");
