title: How to search across all fields when using Hibernate Search
body: <p>I have just changed my search implementation to Hibernate Search 4.5.1.FINAL. I am trying to create a query that search for a word in all the fields. However, I am not able to find anything on how to achieve that. In ElasticSearch you have a <code>_all</code> field. <a href="http://www.elasticsearch.org/guide/en/elasticsearch/reference/current/mapping-all-field.html" rel="nofollow">http://www.elasticsearch.org/guide/en/elasticsearch/reference/current/mapping-all-field.html</a></p>
  
  <p>I am offering an text field that the user can write anything in and then get a result. But I don't know which fields he/she wants to search.</p>
  
  <p>How can I do this in Hibernate Search? I don't want to add a <code>@Field(name="_all")</code> annotation in addition to the regular <code>@Field</code> annotation. How do you do this?</p>
