ElasticSearch/Elastica：搜索包含“and”或其他停用词的确切词语

Question

我试图让ES QueryString匹配包含“and”的搜索词，但我迄今试过的所有内容（尝试不同的分析仪，令牌仪，过滤器）没有工作。在MySQL方面，我要的是：

WHERE field LIKE '%abbot and costello%' 

我已经试过各种配置，这是我目前使用的是什么（因为它“方丈”匹配略有改善（与尾随的空间），但仍然没有它匹配任何东西“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 
); 

这里是我的测试用例字段值：

Abbott and Costello - Funniest Routines, Vol. 

尝试各种分析仪，我似乎无法得到它匹配任何包含“和“

个

您在查询中有错字（雅培缺少第二个T）。你也不需要通过ngram进行搜索。搜索标记器可以是关键字，它仍然适用于短于35个字符的短语。顺便说一句，edgeNGram只会给你尾随通配符。对于前导和尾随通配符，您需要使用nGram滤镜。
