php - Php mysql search - 如果使用复数和单数，搜索不起作用

Question

如果我搜索“销售订单”，它会在结果中获取“销售订单”和“销售订单” 。它也用“s”获取结果。

但是，如果我搜索“销售订单”，它只会获取“销售订单”，但我希望“销售订单”也会获取。

我正在使用 php mysql 查询。

SELECT DISTINCT * FROM wp_posts as p 
    inner join wp_postmeta as pm on pm.post_id = p.ID 
    where (p.post_type = 'abc' or p.post_type = 'xyz') 
    and p.post_title LIKE '%sales order%' 
    or (pm.meta_key = 'xyzkeyword' and pm.meta_value LIKE '%sales order%') 
    GROUP by p.ID 
    ORDER BY p.id DESC

Answer 1

试试这个没有“%”

p.post_title LIKE 'sales order'

Answer 2

我不太确定这个查询，但你可以检查为

SELECT DISTINCT * FROM wp_posts as p 
inner join wp_postmeta as pm on pm.post_id = p.ID 
where (p.post_type = 'abc' or p.post_type = 'xyz') 
and p.post_title LIKE '%sales%' AND  p.post_title LIKE '%order%'
or (pm.meta_key = 'xyzkeyword' and pm.meta_value LIKE '%sales order%') 
GROUP by p.ID 
ORDER BY p.id DESC

或者

SELECT DISTINCT * FROM wp_posts as p 
inner join wp_postmeta as pm on pm.post_id = p.ID 
where (p.post_type = 'abc' or p.post_type = 'xyz') 
and p.post_title LIKE '%sales%order%'
or (pm.meta_key = 'xyzkeyword' and pm.meta_value LIKE '%sales order%') 
GROUP by p.ID 
ORDER BY p.id DESC

Answer 3

你也可以这样尝试

and (p.post_title LIKE '%sales order%'  OR p.post_title LIKE '%sales orders%' )

我希望这能解决你的问题。

Answer 4

use MySQL Full text search,check if FULLTEXT indexes are there

SELECT DISTINCT * FROM wp_posts as p 
    inner join wp_postmeta as pm on pm.post_id = p.ID 
    where (p.post_type = 'abc' or p.post_type = 'xyz')
    match (p.post_title) against ('sales order')
    or (pm.meta_key = 'xyzkeyword' and pm.meta_value LIKE '%sales order%') 
    GROUP by p.ID 
    ORDER BY p.id DESC
