问题描述：

这里是我的索引设置JSON创建索引，当我测试 http://localhost:9200/myIndex/_analyze?text=“测试仪” &仪= nGram_analyzer 我得到了以下异常。Elasticsearch无法找到分析仪，但它没有任何错误

我工作的自动完成功能，是我的指标看起来不错？有没有提高性能的建议？

答

您需要更改settings部分是这样的：（即analysis直接进入settings不得以index）

PUT myindex 
{ 
    "mappings": { 
    "practices": { 
     "properties": { 
     "practiceCity": { 
      "type": "string", 
      "index": "analyzed", 
      "analyzer": "nGram_analyzer" 
     }, 
     "practiceId": { 
      "type": "long", 
      "index": "not_analyzed" 
     }, 
     "practiceName": { 
      "type": "string", 
      "boost": 10, 
      "index": "analyzed", 
      "analyzer": "nGram_analyzer" 
     }, 
     "practicePhone": { 
      "type": "long", 
      "boost": 10 
     }, 
     "practiceService": { 
      "type": "string", 
      "boost": 5, 
      "index": "not_analyzed" 
     } 
     } 
    }, 
    "users": { 
     "properties": { 
     "userCityId": { 
      "type": "long" 
     }, 
     "userCityName": { 
      "type": "string", 
      "index": "not_analyzed" 
     }, 
     "userEmail": { 
      "type": "string", 
      "index": "analyzed", 
      "analyzer": "nGram_analyzer" 
     }, 
     "userFirstName": { 
      "type": "string", 
      "boost": 10, 
      "index": "analyzed", 
      "analyzer": "nGram_analyzer" 
     }, 
     "userId": { 
      "type": "long" 
     }, 
     "userLastName": { 
      "type": "string", 
      "boost": 10, 
      "index": "analyzed", 
      "analyzer": "nGram_analyzer" 
     }, 
     "userMobile": { 
      "type": "string", 
      "index": "analyzed", 
      "analyzer": "nGram_analyzer" 
     }, 
     "userSpecialization": { 
      "type": "string", 
      "boost": 5, 
      "index": "not_analyzed" 
     } 
     } 
    } 
    }, 
    "settings": { 
    "index": { 
     "number_of_replicas": "1", 
     "number_of_shards": "5" 
    }, 
    "analysis": { 
     "analyzer": { 
     "nGram_analyzer": { 
      "type": "custom", 
      "tokenizer": "standard", 
      "filter": [ 
      "nGram_filter" 
      ] 
     } 
     }, 
     "filter": { 
     "nGram_filter": { 
      "max_gram": "20", 
      "type": "edgeNGram", 
      "min_gram": "3", 
      "token_chars": [ 
      "letter", 
      "digit", 
      "punctuation", 
      "symbol" 
      ] 
     } 
     } 
    } 
    } 
}

抱歉这样说......不工作的Val，同样的错误响应。我刚刚复制了您的固定索引设置节点。 –

我已解决问题并更新了我的答案，请再试一次。 – Val

没有先生，它尚未修复，获得相同的错误响应。 –
