title: how to get all docs with acts_as_solr
body: <p>I'm doing something like this:</p>
  
  <pre><code>Item.find_by_solr('name:ab*')
  </code></pre>
  
  <p>and it says it returns 297 results:</p>
  
  <pre><code>=&gt; #&lt;ActsAsSolr::SearchResults:0xb6516858 @total_pages=1, @solr_data={:docs=&gt;[doc1, doc2, doc3...]}, :max_score=&gt;1.6935261, :total_pages=&gt;1, :total=&gt;297}, @current_page=1&gt;
  
  Item.count_by_solr('name:ab*') also returns 297.
  </code></pre>
  
  <p>Yet when iterate it only shows 10 items:</p>
  
  <pre><code>Item.find_by_solr('reference_name:ab*').each do |i| puts i end
  </code></pre>
  
  <p>I tried adding {:per_page=>80} and :limit=>:all but it still shows those 10. Any idea what I'm missing?</p>
