title: SOLR 4.4 indexing incrementally
body: <p>When I kick off a full-import via:</p>
  
  <pre><code>curl -X POST http://_master_host_:_port_/solr/dataimport-xml?command=full-import
  </code></pre>
  
  <p>It is causing our index to update incrementally. So say our inventory count is 900,000, it will suddenly be wiped out and be 400 -> 1000 -> ... -> 900000 (updating incrementally instead of waiting for import to finish then swap out).</p>
  
  <p>I have no idea why it is clearing out our index as previous versions would wait until the import completed before swapping. All our solrconfig settings are the same so I am not sure what is causing this. Any ideas or something I am missing?</p>
