Question

我正在运行SQL Query，如下所示：

SELECT a.id as id,a.name as name , a.price as price , a.saleprice as saleprice, a.images as images, a.slug as slug,a.hover_name as hover_name, MATCH (a.name) AGAINST ('+"blue cushion"') AS title_relevance FROM gc_products a WHERE ( ( ( MATCH (a.name) AGAINST ('+"blue cushion"') ) OR (a.sku like '%blue cushion%') ) and (a.enabled=1) ) ORDER BY title_relevance DESC

但它给了我错误的结果，它也向我展示了名字就像＆＃34;蓝色蜡烛＆＃34; ，＆＃34;红色垫子＆＃34;

我也试过

         MATCH (a.name) AGAINST ('blue cushion')

     MATCH (a.name) AGAINST ('+blue cushion')

MATCH (a.name) AGAINST ('+blue +cushion')

这两个词在一起并不是必要的。它们可以是名称中的任何一个，但两个词必须在名称中。＆＃39; +＆＃39;当我需要至少一次时，符号表示0或更多。

但同样的结果即将到来。我想如果要匹配多个单词，那么它应匹配名称中的所有单词。

 MATCH (a.name) AGAINST ('blue +cushion')

您必须使用IN BOOLEAN MODE修饰符，因为默认情况下MySQL会执行natural language search。

使用此修饰符，某些字符具有特殊含义搜索字符串中单词的开头或结尾。

只需重写您的查询：

SELECT a.id as id,a.name as name , a.price as price , a.saleprice as saleprice,
    a.images as images, a.slug as slug,a.hover_name as hover_name,
    MATCH (a.name) AGAINST ('+"blue cushion"' IN BOOLEAN MODE) AS title_relevance
    FROM gc_products a
    WHERE ( ( ( MATCH (a.name) AGAINST ('+"blue cushion"' IN BOOLEAN MODE) )
    OR (a.sku like '%blue cushion%') )
    AND (a.enabled=1) )
    ORDER BY title_relevance DESC

匹配Mysql没有给出正确的结果
