this bug was previously part of [Issue 57](bug 57)

# Steps to reproduce #

- upload an instance from the ORTHO patient (attached),
- perform the following tools/find request:

```
#!python
curl 'http://localhost:8042/tools/find' --data-binary '{"Level":"Patient","CaseSensitive":false,"Query":{"AccessionNumber":"*","PatientBirthDate":"*","PatientID":"*","PatientName":"*O*","PatientSex":"*","StudyDate":"*","StudyDescription":"*"},"Limit":10,"Since":0}'

```
- the search returns no result because `PatientSex` is missing from the `ORTHO` patient

# additional info #
The spec is not clear about that: http://dicom.nema.org/medical/dicom/current/output/chtml/part04/sect_C.2.2.2.html We should also check how other tools behave in this case.

Note that this also affects the new Orthanc Explorer interface and therefore, some studies might be inaccessible through the web interface.
In this case, I have 3 patients whose name is "MAZY^ALAIN".  Two of them have incomplete tags.  Only one is found in the lookup interface.

"PatientSex" is a mandatory type 2 DICOM tag, as can be seen using dicom3tools:

```text
$ dciodvfy /tmp/CR000000.dcm 2>&1 | grep Error

```

I guess the images from the first comment are invalid as well

images from the first comment where linked to a UI problem that has been solved in https://hg.orthanc-server.com/orthanc/changeset/c9c2faf76bec1b3573d389a744ddae241ea2e037
