title: finding on which page a search string is located in a pdf document using python
body: <p>Which python packages can I use to find out out on which page a specific “search string” is located ? </p>
  
  <p>I looked into several python pdf packages  but couldn't figure out which one I should use. 
  <a href="http://pybrary.net/pyPdf/" rel="noreferrer">PyPDF</a> does not seem to have this functionality and <a href="http://www.unixuser.org/~euske/python/pdfminer/index.html" rel="noreferrer">PDFMiner</a> seems to be an overkill for such simple task. 
  Any advice ? </p>
  
  <p>More precise: 
  I have several PDF documents and I would like to extract pages which are between a string “Begin” and a string  “End” . </p>
