互斥MySQL全文搜索

Question

Suppose I had a MySQL table with the following column: 假设我有一个带有以下列的MySQL表：

   |variables|
1. | 'a'     |
2. | 'a b'   |
3. | 'a b c' |
4. |   ...   |

How can I construct a MySQL Full-Text search that doesn't ignore white space in the column entries? 如何构造不忽略列条目中空格的MySQL全文搜索？

For example, I would like the following query to return only row 1: 例如，我希望以下查询仅返回第1行：

SELECT column FROM table WHERE MATCH variables AGAINST ('a')

As it is, however, this query would return rows 1–3 because all three rows contain the letter 'a'. 但是，由于所有三行都包含字母“ a”，因此该查询将返回第1-3行。

您的搜索规则尚不清楚，但是在这种情况下，正则表达式搜索比全文查询更能为您提供服务。
