ElasticSearch Phrase Suggester不返回任何结果

Question

我使用ElasticSearch 5.1.2作为Heroku的Searchly插件，使用nodeJS包（https://github.com/elastic/elasticsearch-js）。 我正在尝试将菜肴名称与Phrase Suggester相匹配。 我相信我接着写了以下教程https://www.elastic.co/guide/en/elasticsearch/reference/5.1/search-suggesters-phrase.html

我可以在Searchly仪表板中看到我的商店包含数据。 然而，即使在搜索确切的短语时，我的查询也不会返回任何结果。

这是我的设置（CoffeeScript）：

<link href="https://cdnjs.cloudflare.com/ajax/libs/awesomplete/1.1.1/awesomplete.min.css" rel="stylesheet"/>
<input id="myinput" />
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.1.1/jquery.min.js"></script>
<script src="https://cdnjs.cloudflare.com/ajax/libs/awesomplete/1.1.1/awesomplete.min.js"></script>

这是我的疑问：

elasticSearchClient.indices.exists index: 'dishes'
.then (indexExists) ->
  if indexExists
    elasticSearchClient.indices.delete index: 'dishes'
.then () ->
  elasticSearchClient.indices.create index: 'dishes'
.then () ->
  elasticSearchClient.indices.close index: 'dishes'
.then () ->
  elasticSearchClient.indices.putSettings {
    index: 'dishes'
    body:
      settings:
        number_of_shards: 1
        analysis:
          filter:
            shingle:
              type: 'shingle',
              min_shingle_size: 2
              max_shingle_size: 3
          analyzer:
            trigram:
              type: 'custom',
              tokenizer: 'standard',
              filter: ['standard', 'shingle']
            reverse:
              type: 'custom',
              tokenizer: 'standard',
              filter: ['standard', 'reverse']
  }
.then () ->
  elasticSearchClient.indices.open index: 'dishes'
.then () ->
  elasticSearchClient.indices.putMapping {
    index: 'dishes'
    type: 'dishes'
    body:
      properties:
        dishNameMatching:
          type: 'text'
          fields:
            trigram:
              type: 'text'
              analyzer: 'trigram'
            reverse:
              type: 'text'
              analyzer: 'reverse'
        name:
          type: 'string'
          index: 'no'
        flavorId:
          type: 'string'
          index: 'no'
  }

这是我在寻找带有草莓酱的＃34;马铃薯片时得到的结果＆＃34;：

elasticSearchClient.suggest {
  index: 'dishes'
  body:
    text: myText
    dishSuggester:
      phrase:
        field: 'dishNameMatching.trigram'
        size: options.limit or 5
        gram_size: 3
        direct_generator: [
          field: 'dishNameMatching.trigram'
          suggest_mode: 'always'
        ]
        highlight: {
          pre_tag: '['
          post_tag: ']'
        }
}
