Question

例如，我想在标题/描述中搜索“Sprite”，“Pepsi”或“Coke”的所有条目，并输出最后3个结果。

------------------------------------------------
| ID | Title                 | Description     |
------------------------------------------------
| 1  | text text SPRITE text | text PEPSI xxx  |
| 2  | text text text text   | text text text  |
| 3  | text text SPRITE text | text COKE xxxx  |
| 4  | text text text text   | text text text  |
| 5  | text PEPSI text text  | text COKE xxxx  |
| 6  | text COKE text text   | text COKE xxxx  |
| 7  | text text text text   | text text text  |
| 8  | text text text text   | text text text  |
------------------------------------------------

这是最有效的查询吗？

SELECT *
FROM `table`
WHERE title LIKE '%Sprite%' OR description LIKE '%Sprite%'
      OR title LIKE '%Pepsi%' OR description LIKE '%Pepsi%'
      OR title LIKE '%Coke%' OR description LIKE '%Coke%'
ORDER BY 'id' DESC
LIMIT 3;

或者有没有办法用MATCH AGAINST做到这一点？（我找不到办法）..

示例输出：

------------------------------------------------
| 6  | text COKE text text   | text COKE xxxx  |
| 5  | text PEPSI text text  | text COKE xxxx  |
| 3  | text text SPRITE text | text COKE xxxx  |
------------------------------------------------

Answer 1

SELECT *
FROM `table`
WHERE description regexp ('sprite|pepsi|coke')
ORDER BY 'id' DESC

使用SQL一次搜索多个事物的最有效方法？
