is this restriction for a better system performance? i can understandif this is the reason behind it. however, it is kinda inconvenient.
i have an idea (inspired by the legendary hueran bank). people pay tosearch more frequently in a short period of time. charge 1 unit cash orsomething. in this way, users might be more careful when they do theirsearch. this might potentially save system resources.

顶一下，是觉得时间太长了，555555，每次想起来都头大

这个限制确实很烦人，我每次整理版面都是靠搜索来找老帖子的，结果每次都要等好长时间。急死人了，还不错报错的。

搜索过多系统负荷过大，这个暂时就不改了吧
