Mysql在WHERE LIKE中排序优先级

我是MySQL的新手。请帮我找出我做错了什么。 使用这个问题，我尝试对行进行排序，但结果与未排序的结果相同。 下面是一个查询示例：

SELECT * FROM sc_products
WHERE name_ru = 'water' 
OR name_ru like 'water%' 
OR name_ru like '% water%' 
OR name_ru like '\"water%' 
OR brief_description_ru like '%water%' 
OR product_code like '%water%'  
OR product_code in (select product_code from ALLPRODUCTS where searchfilter like '%water%') 
OR product_code in (select product_code from SC_products prd JOIN SC_product_manufacturers mnf ON prd.manufacturerID=mnf.manufacturerID where mnf.filters like '%water%')
ORDER BY CASE
    WHEN (name_ru = 'water' AND 
            name_ru like 'water%' AND 
            name_ru like '% water%' AND 
            name_ru like '\"water%' AND 
            brief_description_ru like '%water%' AND 
            product_code like '%water%') 
    THEN 1
    ELSE 2 
END

我没有找到其他地方回答我的问题。对不起。
