I am sorry that I don't know where to put this post.
I found there was something wrong with the "search function".
For example, I want to search some posts related to mpeg4 video,
So I put mpeg4 in search page, after I got a lot results, about 10 pages for example, however, I can only read 1 or 2 pages, after that if I click next page or page 3 in the bottom of the page, then I was told there are no more posts. It is weird. I found this problem recently, before that, I can read all the posts I searched.
I just ask the admininstrator to check this and confirm what I find and fix it, please.
Thank you in advance.
