In the absence of the search engine you can try replace it momentarily by searching google, you just:
1) Go to Google's address:
Google
2) Make your search this way:
To search for a firmware with arabic language write
'RM-709 arabic firmware - GSM FORUM'
Then you will be redirected to the results like that:
https://www.google.com.br/#q=rm-709+...gsmhosting.com
I hope everything returns to normal as soon as possible.
Good luck!
