Hi Mehdi,
I don't know enough Go to tell if there are problems with your code, but
the rest interface seems to be picky about the headers.
The blurb about the 2 headers below is from
http://www.orientechnologies.com/docs/last/OrientDB-REST.html
I have seen it work without them set, but maybe that's your problem? If you
send the query as the post body, you should not url encode.
All the requests must have these 2 headers:
'Accept-Encoding': 'gzip,deflate'
'Content-Length': <content-length>
