title: C-FIND Study by patient-ID and date
body: <p>I would like to download the chest x-ray file which matches a specified Patient ID and a Study Date from PACS.<br>
  If I specify the date in the C-FIND-Request, I can't get any matched result.<br>
  Could you suggest what's wrong with my query?<br>
  Thank you very much~<br></p>
  <ul>
  <li>I use pynetdicom to interact with GE's PACS.<br></li>
  <li>The example records in PACS are:<br>
   Study Date Modality Patient ID Online<br>
   -------------------------------------------------------<br>
   2021/08/21 XA   12345678 Y<br>
   2021/08/19 US   12345678 Y<br>
   2021/08/11 US   12345678 Y<br>
   2021/08/09 US   12345678 Y<br>
   2021/08/02 US   12345678 Y<br>
   2021/07/16 CR   12345678 Y<br>
   The records from 2021/08/02 to 2021/08/21 are related study.<br>
   My target is the one taken on 2021/07/16.<br></li>
  <li>Start with C-ECHO, then send C-FIND, low priority<br>
  I have tried <br>
  (1) C-FIND under patient root, patient level<br>
  (2) C-FIND under study root, study level<br>
  And if I specify the date(StudyDate = &quot;20210716&quot;), I can't get any matched result.<br></li>
  <li>Following are the log of pynetdicom for C-FIND under patient root, patient level.<br></li>
  </ul>
  <p>(1) Case: condition only on Patient ID<br></p>
