 You may open the OE2 interface directly on a specific study or patient by specifying DICOM Tags directly in the URL.
 e.g::
 
-    http://localhost:8042/ui/app/#/filtered-studies?PatientID=00000169
+    http://localhost:8042/ui/app/#/filtered-studies?PatientID="00000169"
     http://localhost:8042/ui/app/#/filtered-studies?StudyDate=20220512-20220513&ModalitiesInStudy=CR\DX

+By default, OE2 will add a wildcard ``*`` at the beginning and at the end of the search text.  Therefore, searching
+for ``PatientID=1234`` will actually search for ``PatientID=*1234*``.  If you do not want to have these extra wildcards
+added, you should use ``"`` at the beginning and/or at the end of the search text.  Therefore, searching for
+``PatientID="1234"`` will return only the studies whose ``PatientID`` is exactly ``1234``.
+These ``"`` can also be used in the User Interface search fields.
