HAPI FHIR Retrieve Patients
问题
我对HAPI FHIR客户端非常陌生，并且一直在浏览教程和文档，试图帮助我开发的程序，但是当我要查询服务器以搜索由同一医生治疗的患者列表时，我现在陷入了困境。换句话说，我希望用户输入医生的ID号码，系统返回一个包含患者详细信息的列表。当我输入医生的ID号码时，我能够查询服务器以获取所有的就诊记录（Encounters），这些记录都放在一个Bundle中，但我不知道接下来该怎么做。我已经放置了我用来获取Bundle的代码行，并且可以验证它的有效性，因为当我统计Bundle中资源的数量时，我得到了正确的数字。pracID是用户输入的整数。
Bundle response = client.search().forResource(Encounter.class).where(Encounter.PRACTITIONER.hasId(Integer.toString(pracID))).returnBundle(Bundle.class).execute();
我也在IntelliJ中使用Java进行编码，使用的是R4版本的Context客户端。非常感谢您的帮助。提前致谢。

I am very new to the HAPI FHIR client, and have been endlessly browsing tutorials and documentation to try and assist me with my program that I am trying to develop, but I am now stuck when it comes to querying a server to search for a list of Patients that are all being treated by the same practitioner. In other words, I want a user to enter a Practitioner ID number and for the system to return a list of patients with their details. I was able to query the server to get all the Encounters when entering the ID number of the Practitioner, which were all placed into a Bundle, but I have no idea where to go from there. I have placed the line of code I used to get the Bundle and can verify that it works, because when couting the number of resources in the bundle, I get the correct number. pracID is the user-entered integer.
Bundle response = client.search().forResource(Encounter.class).where(Encounter.PRACTITIONER.hasId(Integer.toString(pracID))).returnBundle(Bundle.class).execute();
I am also coding this in Java on IntelliJ, using the R4 version of the Context client. I will highly appreciate any help. Thanks in advance

我认为通往罗马的道路有很多条，但我的第一个天真的方法将是以下内容：您可以尝试使用搜索参数_include递归地查找患者数据。此搜索参数会针对所有与相应主题相关的就诊对象进行搜索：
Bundle response =
client.search()
.forResource(Encounter.class)
.where(Encounter.PRACTITIONER.hasId(Integer.toString(pracID)))
.include(Patient.INCLUDE_ALL.asRecursive())
.returnBundle(Bundle.class).execute();
如果链接可用，则束缚现在不仅应包含就诊对象，还应包含患者对象，可以按以下方式检索以进行进一步处理：
List<Patient> listPatients = new ArrayList<Patient>();
response.getEntry().forEach(entry -> {
if (entry.getResource() instanceof Patient) {
listPatients.add((Patient) entry.getResource());
}
});

I think there are many roads leading to Rome, but my first naive approach would be the following: You could try to find the patient data recursively using the search parameter _include. This search parameter searches all encounter objects for the corresponding Subject:
Bundle response =
client.search()
.forResource(Encounter.class)
.where(Encounter.PRACTITIONER.hasId(Integer.toString(pracID)))
.include(Patient.INCLUDE_ALL.asRecursive())
.returnBundle(Bundle.class).execute();
If links are available, the bundle should now contain not only Encounter objects but also Patient objects, which could be retrieved for further processing as follows:
List<Patient> listPatients = new ArrayList<Patient>();
response.getEntry().forEach(entry -> {
if (entry.getResource() instanceof Patient) {
listPatients.add((Patient) entry.getResource());
}
});
