A couple of months ago Yousef wrote about a search engine called Yamli. For those who dont know yet whats yamli is, here is an excerpt from his post :
“you don’t have to struggle with the spelling, you can type using ur regular Arabish letters (mIRC letters, like the 3 for 3aba3aal and 7 for 7mar) and it will recognize the letters and turns them into arabic letters. 😀 “.
And now google applies this feature in its search engine. CHECK it out.
