全文搜索弹性搜索

Question

我正在尝试使用弹性搜索而不是mysql进行全文搜索（目前它很慢），所以我只是制作演示而且我发现mysql表现更好。

但我怀疑我做错了什么

到现在为止我做了什么： -

本地主机：9200 / elastic_analysis_pattern / _settings

{
  "elastic_analysis_pattern": {
  "settings": {
     "index": {
       "creation_date": "1459959233955",
       "analysis": {
          "filter": {
            "edge_ngram": {
               "min_gram": "2",
               "side": "front",
               "type":  "edgeNGram",localhost:9200/elastic_analysis_pattern/_mapping/
              "max_gram": "20"
            }
         },
         "analyzer": {
             "pattern_index": {
                 "filter": [
                    "lowercase",
                    "stop",
                    "edge_ngram"
                  ],
                "tokenizer": "pattern_token"
             },
             "pattern_search": {
                 "filter": [
                   "lowercase",
                   "stop"
                  ],
                "tokenizer": "whitespace_token"
             }
         },
        "tokenizer": {
            "whitespace_token": {
                "type": "whitespace"
             },
           "pattern_token": {
                "pattern": "[^\\p{L}\\d]+",
                "type": "pattern"
            }
         }
      },
      "number_of_shards": "5",
      "number_of_replicas": "1",
      "uuid": "109pq9KfTVq32rIydKMPtg",
      "version": {
         "created": "2020199"
       }
    }
 }
 }
}

本地主机：9200 / elastic_analysis_pattern / _mapping /

{
  "elastic_analysis_pattern": {
  "mappings": {
    "search_analysis": {
       "properties": {
          "search": {
            "type": "string",
            "analyzer": "pattern_index",
            "search_analyzer": "pattern_search"
           }
        }
     }
  }
}
}

我正在搜索的查询是： -

{
   "query" : {
          "bool" : {
                    "must"  : {
                        "query_string"  : {
                            "query" : "sho",
                            "default_field"    => "search"
                        }
                    }
                }
            },
            "size"  => 10
   }  

和mysql查询是：

SELECT SQL_NO_CACHE * FROM internet_ads WHERE (MATCH (search) AGAINST (' +sho*' IN BOOLEAN MODE)) LIMIT 0,10

我正在使用大约有60,000行的数据库进行测试

exectution时间

弹性时间 = 0.034985065460205 mysql时间 = 0.01869797706604

任何人都可以告诉我，如果我在这里做错了。

非常感谢任何帮助。
