前言

现在已经建好了相应的索引，现在要使用相应的api实现搜索提示功能。

引入依赖

<dependency>
      <groupId>org.codelibs.fess</groupId>
      <artifactId>fess-suggest</artifactId>
      <version>5.6.0</version>
 </dependency>

使用CompletionSuggester实现搜索提示

之前在建立索引时，设置了五个不同的分词配置，我们可以使用不同的分词配置，对title和content进行匹配，

/*
	1. 全中文词汇 采用ik-word ik分词 和standard 查询。
	2. 含有英文和中文的 采用 s-pinyin keyword_pinyin
	3. 全英文的就使用拼音

处理搜索结果：

    private void handlerSuggest(Suggest suggestions,Map<String,Integer> suggestMap,String suggestName){
   
        List<? extends Suggest.Suggestion.Entry<? extends Suggest.Suggestion.Entry.Option>> results = suggestions.getSuggestion(suggestName).getEntries();
        for (Suggest.Suggestion.Entry<? extends Suggest.Suggestion.Entry.Option> op : results) {
   
            List<? extends Suggest.Suggestion.Entry.Option> options = op.getOptions();
            for (Suggest.Suggestion.Entry.Option pp : options) {
   
                if (suggestMap.containsKey(pp.getText().toString())) {
   
                    suggestMap.put(pp.getText
