mysql查询查看搜索速度慢

Question

我们的搜索速度很慢。我们无法在视图上定义索引..请帮助我们如何改进..下面的查询花费了 33.3993 秒。

SELECT 
     `v_cat_pro`.`product_id`, `v_cat_pro`.`msrp`, 
FROM 
     `v_prod_cat` AS `v_cat_pro`
WHERE 
     (product_status="1" and msrp >0 AND (search_text = 'de') )
ORDER BY 
     `msrp` ASC LIMIT 50

如果您在要搜索的列上为“v_prod_cat”表添加索引，那么这应该有助于加快您的查看速度。
