5.程式碼

    CompletionSuggestionBuilder completionSuggestionBuilder = new         
    CompletionSuggestionBuilder("complete");
    completionSuggestionBuilder.text(paramMap.get("text"));
    completionSuggestionBuilder.field(paramMap.get("field"));
    completionSuggestionBuilder.size(10);

    IElasticsearchClient client = index.getIndexClient();
    CompletionSuggestionBuilder completionSuggestion = completionSuggestionBuilder 
    SuggestResponse resp = client.prepareSuggest(realIndexName)
            .addSuggestion(completionSuggestion).execute().actionGet();

    List<? extends Suggest.Suggestion.Entry<? extends Suggest.Suggestion.Entry.Option>>            list =         response.getSuggest().getSuggestion("complete").getEntries();
    List<String> suggestList = new ArrayList<String>();
if (list == null) {
        return null;
    } else {
for (Suggest.Suggestion.Entry<? extends Suggest.Suggestion.Entry.Option> e : list){
for (Suggest.Suggestion.Entry.Option option : e) {
                suggestList.add(option.getText().toString());
            }
        }
