I tried it one by one and summarized the code of each search engine as follows:
Google: http://www.google.com/search? Hl = en & AQ = F & btng = Google Search & Q = % us
Google: http://www.google.cn/search? Client = aff-CS-worldbrowser & forid = 1 & Ie = UTF-8 & OE = UTF-8 & HL = ZH-CN & Q = % us
Google pictures: http://images.google.com/images? Hl = ZH-CN & Q = % us
Google Music: http://www.google.cn/music/search? Q = % US & AQ = f
Baidu: http://www.baidu.com/s? WD = % s
Baidu MP3: http://mp3.baidu.com/M? F = Ms & Rn = & Tn = baidump3 & Ct = 134217728 & word = % s
Thunder resource search (DOG): http://www.gougou.com/search? Search = % s
Microsoft Bing: http://www.bing.com/search? Q = % US & filt = All & MKT = ZH-CN
I tried Bing for a long time. The last one & MKT = ZH-CN can only search for English if it is not added. The Chinese search is garbled. These strings are not necessarily the best, but can be used.
