Elasticsearch短语建议collat​​e返回false，即使查询返回结果

Question

所以我有以下短语建议模板：

PUT /_search/template/DidYouMean
{
  "template": {
    "size": 0,
    "suggest": {
      "DidYouMean": {
        "text": "{{SearchPhrase}}",
        "phrase": {
          "field": "_all",
          "analyzer": "simple",
          "size": 50,
          "real_word_error_likelihood": 0.9,
          "max_errors": 0.5,
          "gram_size": 3,
          "direct_generator": [
            {
              "field": "_all",
              "suggest_mode": "always",
              "min_word_length": 3
            }
          ],
          "collate": {
            "prune": true,
            "query": {
              "match": {
                "_all": {
                  "query": "{{suggestion}}"
                }
              }
            }
          }
        }
      }
    }
  }
}

我使用此查询运行它：

POST /my_index/_search/template
{
  "template": {
    "id": "DidYouMean"
  },
  "params": {
    "SearchPhrase": "unileve"
  }
}

我希望"collate_match": true得到联合利华（一家公司）的结果，然而，它会带回false。我得到了这个，即使我期待联合利华真的来到这里：

{
   "took": 25,
   "timed_out": false,
   "_shards": {
      "total": 5,
      "successful": 5,
      "failed": 0
   },
   "hits": {
      "total": 220692,
      "max_score": 0,
      "hits": []
   },
   "suggest": {
      "DidYouMean": [
         {
            "text": "unileve",
            "offset": 0,
            "length": 7,
            "options": [
               {
                  "text": "unilever",
                  "score": 0.016954133,
                  "collate_match": false
               },
               {
                  "text": "unilevers",
                  "score": 0.005391976,
                  "collate_match": false
               },
               {
                  "text": "unilet",
                  "score": 0.00062763924,
                  "collate_match": false
               },
               {
                  "text": "uniline",
                  "score": 0.00062518474,
                  "collate_match": false
               },
               {
                  "text": "unilerver",
                  "score": 0.00055350363,
                  "collate_match": false
               },
               {
                  "text": "uniliver",
                  "score": 0.00055350363,
                  "collate_match": false
               },
               {
                  "text": "unielever",
                  "score": 0.0005243993,
                  "collate_match": false
               }
            ]
         }
      ]
   }
}

现在当我自己运行相同的查询时，它会带来结果。

POST /my_index/_search
{
  "query": {
    "match": {
      "_all": {
        "query": "unilever"
      }
    }
  }
}

它确实带来了结果。

         }
      ]
   }
}

我是否误解了整理的目的？或者我只是在做一些完全错误的事情。请指教。

Elasticsearch版本：1.7.3

Answer 1

我能够自己解决这个问题。

的问题：

1. 我正在创建一个模板。
   预期
   • {{suggestion}}作为参数，未提供
   • 所以我明白它是在没有它的情况下渲染而且匹配查询是针对没有
   运行的

我是如何解决的？

查询模板需要以某种方式呈现{{suggestion}}，所以我不得不逃避这些字符。见：

PUT /_search/template/DidYouMean
{
  "template": {
    "size": 0,
    "suggest": {
      "DidYouMean": {
        "text": "{{SearchPhrase}}",
        "phrase": {
          "field": "_all",
          "analyzer": "simple",
          "size": 50,
          "real_word_error_likelihood": 0.9,
          "max_errors": 0.5,
          "gram_size": 3,
          "direct_generator": [
            {
              "field": "_all",
              "suggest_mode": "always",
              "min_word_length": 3
            }
          ],
          "collate": {
            "prune": true,
            "query": {
              "match": {
                "_all": {
                  "query": "{{=<% %>=}}{{suggestion}}<%={{ }}=%>"
                }
              }
            }
          }
        }
      }
    }
  }
}

How does one use a literal {{ in a Mustache template?回答了如何做到这一点。

现在它将此作为参数呈现，而不是期望在

中传递某些内容
