  -	}
  +{

positive.code: Get all content of 'provider type' passed in task configuration from DCP persistent store (so given provider type must be defined as persistent) and store/update it into DCP search index.  
  
  ```
  	{
  	  "dcp_content_type" : "jbossorg_blog"  
  	}

negative.code: Get all content with `dcp_project` matching values passed in task configuration from DCP search indices, run all data normalizations on it, and update it back into DCP search index. Used for example when project code or project name changes in DCP project configuration, so we need to update content in search indices for it. 
  
  ``` 
  {
    "project_code" : ["jbosstools", "jbossas7"]  
  }
  ```
