Question

elasticsearch的新手，正在研究术语建议和短语建议功能。我创建了以下脚本，并在kibana中执行了该脚本，它工作得非常好。我想使用Java API来实现相同的功能。

请在下面找到我的脚本。

get product/_search
{
  "suggest" : {
    "autocomplete" : {
      "text" : "pressure",
      "term" : {
        "field" : "product_attr_value",
        "suggest_mode" : "popular"
      }
    }
  },
  "size" : 0
}

是将ES 6.2.3版本与RestHighLevel客户端一起使用。

已经形成了uggestinationBuilder查询，并且还能够从查询中获取响应。但是我如何在列表中设置这些响应。从下面的代码中，尝试访问来自SearchHit的响应，并尝试在List中进行设置，但是在打印列表大小时，其结果为0。

  SearchSourceBuilder searchSourceBuilder = new SearchSourceBuilder();
  SuggestionBuilder termSuggestionBuilder =
      SuggestBuilders.termSuggestion("product_attr_value").text("valv").suggestMode(SuggestMode.ALWAYS); 
  SuggestBuilder suggestBuilder = new SuggestBuilder();
  suggestBuilder.addSuggestion("suggest_product", termSuggestionBuilder); 
  searchSourceBuilder.suggest(suggestBuilder);
  searchSourceBuilder.size(10);
  suggestionRequest.source(searchSourceBuilder);

  try
    {
      searchResponse = SearchEngineClient.getInstance().search(suggestionRequest);
    }
    catch (IOException e)
    {
      e.getLocalizedMessage();
    }

    SearchHit[] searchHits1 = searchResponse.getHits().getHits();
    long totalHits = searchResponse.getHits().totalHits;
    System.out.println("Keyword Search Hits....---->"+totalHits);

    List<Suggestion> suggestionTermList=new ArrayList<Suggestion>();
    Map<String, Object> sourceAsMap = null;
    for (SearchHit hit : searchHits1)
    {
      sourceAsMap = hit.getSourceAsMap();
      suggestions = new Suggestion();
      suggestions.setSuggestionString(String.valueOf(sourceAsMap.get("text")));
      suggestionTermList.add(suggestions);
    }
    System.out.println("suggestion response --->"+searchResponse.toString());
    System.out.println("Suggestion List Size --->"+suggestionTermList.size());

请在下面找到我的回复：

{"took":6,"timed_out":false,"_shards":{"total":5,"successful":5,"skipped":0,"failed":0},"hits":{"total":0,"max_score":0.0,"hits":[]},"suggest":{"suggest_product":[{"text":"valv","offset":0,"length":4,"options":[{"text":"valve","score":0.75,"freq":15218},{"text":"val,","score":0.75,"freq":169},{"text":"valvw","score":0.75,"freq":2},{"text":"val","score":0.6666666,"freq":1532},{"text":"vlv","score":0.6666666,"freq":1145}]}]}}
