ElasticSearch - 在not_analyzed上不区分大小写的搜索

Question

$results=$client->search([ 
       'index' => 'my_index', 
       'type' => 'my_type', 
       'body' => [ 
        'query' => [ 
         "multi_match" => [ 
          "fields" =["column1","column2","column3"], 
          "query" => "Test", 
          "type" => "phrase_prefix" 

         ] 
        ] 
       ] 
      ]); 

我正在使用elasticsearch和laravel.How如何使上面的代码不区分大小写。

Answer 1

将以下设置添加到您的索引。这将采取不区分大小写。

PUT - /index_name/_settings 

{ 
    "settings": { 
    "analysis": { 
     "analyzer": { 
     "custom_ta_analyzer": { 
      "tokenizer": "keyword", 
      "filter": [ "lowercase" ] 
     } 
     } 
    } 
    } 
}
