title: unknown command error while posting files to solr
body: <p>I am trying to post the following json format of the file to solr</p>
  
  <p><code>{"userName": "Bill", "stars": 4, "review_id": "-TsVN230RCkLYKBeLsuz7A", "type": "review", "business_name": "Eric Goldberg, MD", "user_id": "zvJCcrpm2yOZrxKffwGQLA", "text": "Dr. Goldberg has been my doctor for years and I like him.  I've found his office to be fairly efficient.  Today I actually got to see the doctor a few minutes early!  \n\nHe seems very engaged with his patients and his demeanor is friendly, yet authoritative.    \n\nI'm glad to have Dr. Goldberg as my doctor."}</code></p>
  
  <p>However I get the error </p>
  
  <p><code>Response: {"responseHeader":{"status":400,"QTime":32},"                                                                                                                error":{"msg":"Unknown command 'user_name' at [12]","code":400}}</code></p>
  
  <p>while I am trying to do</p>
  
  <p><code>post.sh -c coreName fileName.json</code></p>
  
  <p>This is driving me crazy. I have unloaded the core and created it again to see if previous attempts to post files is causing this error. But that did not help.</p>
