Thank you for your comment. Due to historical reasons, Our organization uses trunk version of Solr-4.0, which is a bit old and unofficial version. And edismax always returns 1/2 as a coordination value. So I wanted to make sure what this value would be like. This will be a good reason to upgrade our system to Solr 4.3 or later version.
