Should I use Entity Views Attach module to solve my problem
I suspect you might get a better answer if you were to say more about what you are trying to achieve than how you are doing so. 

For example, reading between the lines of your question I wonder if you are working on some sort of faceted search? In which case I'd recommend you look at Search API. And this may be of interest: http://ygerasimov.com/ajaxified-solr-search-drupal-search-api-views-panels
