在这个 ssql 查询中，我%在AGAINST子句中使用了 a。

            SELECT firstname,lastname,middlename,company_name, 
                    primary_emailaddress,alternate_emailaddress,personal_address_line1,

            ) 
            AND addressbook_id = 4

两者都不会返回内容精确等于 atleast 的位置someemail@email.com。它通过 com 或电子邮件或其他方式返回所有内容。我需要做哪些改变？FULLTEXT匹配列上有一个索引。

最好将地址放在引号中，并且根本不使用通配符：

AGAINST ('"someemail@email.com"' IN BOOLEAN MODE)

像那样。

而且我认为您不需要布尔模式。

您的全文搜索不起作用，因为@and .（实际上是大多数非字母数字字符）是单词分隔符。因此 1. 电子邮件被索引为三个单独的单词和 2. 单词分隔符从您的搜索字符串中被忽略。

只需在列上创建一个常规的多列索引，然后使用标准搜索LIKE：

WHERE firstname LIKE 'someemail@email.com%' OR ...

此查询将能够使用索引并且搜索将非常有效。

另外，摆脱这些REGEXP(). 它们是无用的（冗余的）并且会扼杀你的表现（不能使用索引）。
