ElasticSearch/Elastica：搜索包含「and」或其他停用詞的確切詞語

Question

我試圖讓ES QueryString匹配包含「and」的搜索詞，但我迄今試過的所有內容（嘗試不同的分析儀，令牌儀，過濾器）沒有工作。在MySQL方面，我要的是：

WHERE field LIKE '%abbot and costello%' 

我已經試過各種配置，這是我目前使用的是什麼（因爲它「方丈」匹配略有改善（與尾隨的空間），但仍然沒有它匹配任何東西「和」：

$eI->create(array(
    'analysis' => array(
     'analyzer' => array(
      'indexAnalyzer' => array(
       'type' => 'custom', 
       'tokenizer' => 'SQLedgeNGram', 
       'filter' => array(
        'lowercase', 
       ), 
      ), 
      'searchAnalyzer' => array(
       'type' => 'custom', 
       'tokenizer' => 'SQLedgeNGram', 
       'filter' => array(
        'lowercase', 
       ), 
      ) 
     ), 
     'tokenizer' => array(
      'SQLedgeNGram' => array(
       'type' => 'edgeNGram', 
       'min_gram' => 2, 
       'max_gram' => 35, 
       'side' => 'front' 
      ), 
      'standardNoStop' => array(
       'type' => 'standard', 
       'stopwords' => '' 
      ) 
     ) 
    ) 
), true 
); 

這裏是我的測試用例字段值：

Abbott and Costello - Funniest Routines, Vol. 

嘗試各種分析儀，我似乎無法得到它匹配任何包含「和「

個

結果：

您在查詢中有錯字（雅培缺少第二個T）。你也不需要通過ngram進行搜索。搜索標記器可以是關鍵字，它仍然適用於短於35個字符的短語。順便說一句，edgeNGram只會給你尾隨通配符。對於前導和尾隨通配符，您需要使用nGram濾鏡。
