title: Text indexers (for python) with inbuilt support for doc, docx and pdf files
body: <p>I am currently on the lookout for a text indexer for my python program. I shortlisted Solr, a Lucene project and Whoosh, which is native to python. I searched a lot of documentation on support for doc, docx and pdf files, and Solr kept pointing me to the Tika package, a version of which is integrated with Solr.</p>
  
  <p>The results dont mention in certain terms if any package has <strong>inbuilt support for the three formats</strong>. Does Whoosh and Solr support them? Which other open-source indexer natively reads these formats?</p>
