I understand the Admin has made great efforts for the development of new website. Some of these new features, such as classification of deals, merchant filter and hot/ new/ discussed / custom tab, are quite nice. But there arise also many bad things at the same time, such as the text of first page cannot be selected, no the last post time is shown, posting is not as straightforward as before, and so on.
As for search which is very important to find deal information, there are three main issues. First, all items matching any one of the key words will come out. If quotation is used, the order of the key words needs to be absolutely correct. It seems that the new website does not support "AND", that is match all keywords, but they may appear in different positions.
Second, the search misses a lot of posts matched, whether these items are old or new.
Third, the old website has a very nice feature: the phrase matched in the result is highlighted in colour. Unfortunately, however, this is missed in the new one.
